To install the Blend Door Actuator in 2004 Ford Explorer Tools needed: 7 mm socket 8 mm socket 10 mm socket Socket wrench with extension bar Long stem 8 mm box wre…nch Large flathead Screw drive You will need to remove all the following parts. Please be careful while you are removing these parts for wires may be attached and you do not want to break anything. 1. Remove the counsel; first remove the rubber pallets inside the cup holders then remove the screws that will be exposed. Use the screw driver to gently pry the cup holder saddle from the counsel. Be aware that there is a wire connected to the cigarette lighter. 2. Remove all screws holding the armrest in place. There are also two plugs at the foot of the armrest one on the driver side and one on the passenger side. Use the screw driver to gently pry this plugs out (they pull out and push in). Once you have removed all of this, lift the armrest up and pull back you remove it completely. 3. Using the screw driver again, gently pry the dash cover from around the radio and temperature controls. This snaps in and out. Once it is out, disconnect all wiring. 4. Now remove the radio. 5. From under the steering column, remove, remove the undercover panel. 6. Now remove the top panel. There is a leather skirt connected to the steering column that snaps to the steering column that also needs to be removed. You may have to put the gear shift in D3 to remove this piece. There are also wires attached so you have to be gentle with this piece. Once you have this out, disconnect the wires and set aside. 7. Now you ant to remove the control panel. You only want to loosen it then move it to the side. DO NOT try to take it out completely. There is a fine cable attached that cannot be removed that you do not want to break. Once the panel is loose, you can move it to he side. The opening it creates will give you clear access to the Blend Door Actuator. 8. Back down on the driver side, remove the black air duck. 9. Here is a tricky maneuver: there is a 7mm screw located in a tight spot under the steering column where the panel that is blocking the view of the Blend Door Actuator meets the dashboard. You cannot see the screw but you can feel it and it is easily accessible with a 7mm socket and wrench. Once this is removed, it will allow you enough pull to remove the Blend Door Actuator once it is lessened. This eliminates any cutting to the dash. 10. Now you are ready to start the process to remove the Blend Door Actuator. Using you 8mm box wrenches remove the three screws holding it in place. You may be able to use your socket wrench on one of them. Once you have removed the three screws, the Bend Door Actuator is ready to come out. Since there is a long stem on the Actuator, there is not enough room for it to back out, so you will have to pull the panel the we spoke of earlier just a little to give it room to pull completely out. 11. Disengage the wire from the Actuator (you can do this before you take it out as well) 12. Installing the new Actuator is also tricky; it has to line up with the gear inside the airflow system. It takes some patience but it can be done. You have access through the opening by the control panel and from under the dash. Take your time to line up the gear. It takes a little pushing to get it to go in place. This is a tedious job and will take anywhere from four to six hours if you are doing this for the first time. Be patient and take small breaks to relax your muscles. You will not need to remove the glove box. However, if the bend door is open, you can access it through the glove box to close it which will help with installation of the new Actuator. The closed position is when the bend door towards the seat. You cannot see it you can only feel the position of the bend door.
The blend door regulates heat and AC in today's automobiles. Generally the system is set up with air always flowing through the AC evaporator coils, and the compressor is eith…er on or off, cooling or neutral under system control. Now the air flowing through the evaporator is either directed into the vent system, or directed through the heater core and into the vent system. The blend door regulates the amount of air that is allowed to go through the heater core. For AC, the compressor is on and the blend door blocks air flow through the heater core. For heat, the compressor is off and the blend door diverts air through the heater core. Those are the two extremes, and exacting temperature control is achieved by having the blend door in intermediate positions between the two extremes. Remember the slide bar on the AC control panel on older cars? That slide lever was connected by cable to the blend door and temperature control was achieved by sliding the lever. On modern automobiles, that function has been transferred to computer control, using a pseudo stepper motor to control the blend door. On late 90 and early 00 cars, the motor was connected to the same plastic blend doors that were used with the slide scenario and there is a recurring problem over time with the motor being too strong and breaking the plastic blend door, leaving no control over temperature. The fix is to remove the heater box, which is a very involved operation, and replace the plastic door(which WILL break again over time).

For the 99/04 WJ Jeep Grand Cherokee there are two ways. One is to remove the dashboard and HVAC box from the vehicle. The other way to replace the blend doors is by cutt…ing an access hole. A short version of how the access hole repair is done. Disconnect the Negative battery cable. Lower the glove box - by hand Remove the actuator motor - You will need a Phillips screw driver Cut an access hole in the plastic HVAC box - I supply a multi-purpose cutting bit, you will need a rotary type of cutting tool, like a Dremel, RotoZip, etc. Or you could do the cutting by hand with any type of small cutting tool, it will just take longer doing it by hand. Or some customers used a narrow pointed soldering iron! Remove the broken blend doors - by hand Install the new aftermarket access hole blend door kit - easy, just slide the new doors in place - NO screws or other fasteners needed. Close the access hole - Replace the wall piece of plastic you cutout - Apply an aluminum tape to cover the groove made by cutting the wall. Replace the actuator motor. Close the glove box - Your Done! It is almost as easy as what you just read, the hardest and the most time consuming thing to do is cut the access hole. The job should take between 30 minutes to 1 ½ hours. Depending on how long it takes you to gather your tools, etc.
A blend door is short for Blend Air Door. There are other names such as temperature door, etc.. The blend door, blends or mixes the hot air with the cold air. There usually is… an actuator motor that opens and closes the blend door a little at a time to adjust how much hot air and cold air to mix for the temperature setting you have chosen. If your blend door or doors are broken sometimes you will only get cold air coming thru the vents or maybe just hot air with no air conditioning. For more information on the fault codes, etc for the Jeep Grand Cherokee blend door problems, checkout the Blen Dor Store on Ebay. There is an easy blend door replacement kit with only two parts to install. No Dashboard Removal. The Blen Dor kit is guaranteed for as long as you own the vehicle. For more information try a search for Blen Dor . Close, but not exactly. On most modern vehicles, air is constantly blown through the AC evaporator core and then the blend door can divert some or all of the air through the heater core. In full AC mode, the blend door is closed against the heater core inlet and all air flows around the heater core and directly into the vent system. In heater mode, the compressor is deactivated and the air flowing through the evaporator core has no temperature change. As before, the blend door will now direct some or all of the air flow through the heater core and into the vent system. In the old days, the blend door was controlled by a slide lever on the AC panel which was connected to a cable that ran to the blend door. In the mid 90's most automotive companies went to computer control over the blend door, using a pseudo stepper motor to control the door. A common design flaw in these systems is the end point detection for door movement. For a computer algorithm to control the door, it has to "know" when the door is closed against the heater core or blocking the free flow of air through the vent system. This is done by driving the motor and door to a stall point and detecting a voltage surge from the motor as a digital signal indicating the end extent of movement. The catch is that over time the plastic doors cannot withstand the over-stress of the calibration routine and will break. When this happens, all control over heat and AC is lost. The problem is common on multiple vehicles and HeaterTreater has built a line of products for the most severe cases. We are always looking for additional applications for our repair technology and would be happy to discuss how we can provide a solution for your particular issue.
The blend door sits vertically in the heater box behind the glove box. If you fully open the glove box, you can see the actuator motor on top of the heater box in the upper …left hand corner. On the bottom of the box is a "pedestal" that is the bottom axle point for the blend door. The door axis is between the motor axle and the pedestal.

Ford changed the plenum box in the Explorer in 2003 and the system is completely different from the previous models. However, the 03+ model years suffer from a similar b…lend door problem as the earlier models. The early models have a wear-out problem with the door breaking from constant stress of calibration. The newer model has a problem with the design of the system forcing the door out of alignment when it is moving. The stress is constant and results in a broken door sooner than the typical wear-out mechanism on the earlier models. The technical explanation is a little involved without pictures and arrows. Check the Tech section on heatertreater.net for pictures and a full engineering evaluation of the system.
Check your guage light dimmer wheel ( just to the right of your headlight switch ) to see if it has been rotated all the way up - that turns on your interior lights…. Also , if you are getting a door ajar warning light in your gauge cluster you could have a door ajar switch sticking inside one of your doors , liftgate , or for the liftgate glass
The factory method requires removal of the dash and heater box to replace the plastic door with another plastic door. HeaterTreater has a new product to repair the 02-…08 Explorer without removing the dash, and replacing the door with metal that will outlast the Explorer. Check HeaterTreater.net.
The Grand Marquis uses the same HVAC system as the Ford Taurus and Mercury Sable and all three automobiles suffer from the same blend door failures. The actuator is lo…cated on the front side of the plenum box and you can see it if you fully open the glove box and look to the left over the transmission tunnel. The recommended dealer fix is to remove the dash and plenum box and replace the plastic door. There is a kit on Ebay from HeaterTreater that offers a cheap easier fix for this problem.
Assuming you are going to replace the 99/04 Jeep Grand Cherokee blend doors yourself. You would start by disconnecting the negative battery cable. If you are going to remo…ve the dashboard, etc to replace the blend doors. some websites give you complete instructions with plenty of pictures. It will take the average person with little or no auto repair skills approximately 12 to 16 hrs. The vehicle will have to be taken to a shop that can recover the refrigerant before you start removing the dashboard and HVAC box.. If you are going to do the type of repair where you cut an access hole in the side of the HVAC box. A short version of how the access hole repair is done. Disconnect the Negative battery cable. Lower the glove box - by hand Remove the actuator motor - You will need a Phillips screw driver Cut an access hole in the plastic HVAC box - I supply a multi-purpose cutting bit, you will need a rotary type of cutting tool, like a Dremel, RotoZip, etc. Or you could do the cutting by hand with any type of small cutting tool, it will just take longer doing it by hand.

Check for a full explanation of the problem and repair process. Again disconnect the negative battery cable first. This type of repair takes an average of one hour to complete. The work is done behind the glove box. You would cut a 5" x 3" access hole. Remove the broken plastic blend doors, etc Install the new aluminum blend doors, drive connector with stop limited pin. Replace the cutout section and apply an aluminum foil tape on the cut line.
Blend Door Problem Your problem sounds like the common blend door problem on the Ford Expeditions, and Ford Explorer. The door is on a vertical axis and when it brea…ks, it can swing back and forth randomly giving heat or AC or nothing. The difference on acceleration is the force placed on the door swinging it one direction. You can check the operation by fully opening the glove box, removing the actuator motor on top of the plenum box and examining the blend door axle (the actuator is under the unit on top of the hump behind the flexible black plastic cover. It is on top of the unit, behind the glove box in the 2002 F-350 though). Pictures of the common fail signature are available on the Related Links below. There are several "free" fixes that mostly are worth what you pay for them. The solution on the web site is solid and proven over hundreds of vehicles and will resolve the problem once and for all.
The actuator is located on top of the heater box and can be accessed by fully opening the glove box and looking in the upper left hand corner. Generally, the actuator …motor is not the problem, but a broken blend door. For information on how to diagnose and fix the problem, you can check at www.heatertreater.net. This is a very common problem and the fix is very expensive at the dealer. HeaterTreater is a cheap, easy alternative. cgallen
The blend door actuator on the late model Chevy Tahoe is located behind the dash in the glove box area. Broken blend doors and broken blend door actuators are a very common pr…oblem among Chevy Tahoe, Suburban, and Silverado models. Typically, to repair a broken blend door, a mechanic will disassemble the dash and replace the plenum box. It is an expensive and labor intensive repair. There are also some DIY solutions such as the heatertreater that provide hardware and instructions for performing the repair by removing the glove box rather than the entire dash. It is worth looking into if you think you have a broken blend door.

There is no significant power at the three wire plug at the control knob, the three wires are directly wired to a potentiometer. In the five wire plug on the actuator there is… a ground and twelve volts. To test knob, use a multimeter to check for changes in resistance from the middle to the outsides, and for a constant resistance on the outsides. Use a voltmeter to check for 12 volts at the actuator plug, hooking to the two wires that are diff colors than the three that go to the control knob. If you have 0 volts with key in run position, you prolly have blown fuse. The knob resistance can be checked regardless of key position. If turning the knob varies the resistance, and you have twelve volts in run, then your actuator is probably bad. iF turning the knob yields no change in resistance, than the knob is slipping and not turning the shaft it sits on.
Its behind the radio/CD player. To service it, you must spend 3 hours taking everything apart to get to it.
