If the original diagnosis was to change the water pump to repair the blower then you may want to look for a different mechanic. The blower motor could be shot or look for loose wires under the dash or hood or perhaps a blown fuse in the fuse panel. If its a matter of heat in the vehicle then perhaps a new thermostat is in order. There is no relationship between the two mechanically. One of two scenarios happened, When the pump was changed there was somthing disconnected in regards to the blower motor, possibly accidently or possibly as part of the R & R procedure and not re-connected. The second scenario is that you have a 10 year old blower motor and 10 year old components for that system that have failed just as your pump did. WHAT WAS THE ORIGINAL COMPLAINT? Poor heat, a belt that came off or Leaking coolant. Water pump diagnosis is not rocket science in most cases. It is very rare that a water pump is the cause of poor heat and would be quite surprised if this was the original complaint. IF a shop knows this isn't the problem they also know they are going to have to call you back because it didn't fix the problem. I Assure you they don't want to do that as there is enough stress in this industry without having to add to the paranoia of getting "ripped-off". Your particular car may fall into a small group of rivieras and Auroras from 1995 that the blower will not turn on if the coolant temperature does not exceed 108 F. under particular circumstances. The Vin Breakpoints are S4100000 thru S4113711.

Blower motor control relay under dash behind blower motor is bad or has water in it from cabin filter port.

User Avatar

Yes. Hot water comes from the water heater. The blower motor propels warm air around the house through the duct-work, but is not connected to the hot water heater in any way.

wife having same problem changed 2 motors water is leaking from topside somewhere into the blower motor put pin holes to make sure and was right now passenger side gets wet when rains from water dripping can't find out how it's getting but the motor still going

The car heater is a vague question. The heater core is not fused, it is like a mini radiator. The blower motor for heat/AC is fused. The selector blower motor resistor is fused in line with blower motor. Now if you lost heat, the water pump is belt driven, not fused.

The Blower motor for the E320 is located on the upper front left side of the engine directly above the water pump. The blower motor is NOT in the engine compartment! The "blower motor" above the water pump is the EGR/Smog pump, part of the emissions system. The actual blower motor for the HVAC system is under the dash, above your feet on the passenger side of the car, just remove the panel and look up. The filters are located behind the glove box (which has to be removed to access the filters). They clog and don't allow the air to blow and eventually will burn out the regulator on the blower motor itself. There are also 2 separate charcoal filters next to the blower motor under the dash that filter smog from the cabin, these are not as crucial to replace, but should be done at some point. (total of 4 filters 96-02 Eclass).

2004 Pontiacs have a water problem. Water gets into the blower motors and into the blower motor control module and causes this problem.Remove the screws that hold the motor to the dash and see if motor is rusty if it is replace it.If no rust is there replace module.

check your blower motor, located under the dash board. its on the passenger side. if the leak is on the drivers side, i have no clue. but my hubby's car is leaking water from the blower motor on the passenger side. found out at the car wash...

Your A/C drain plug is clogged causing water to leak into the blower motor which causes a short. To resolve jack up the car and properly support it using axle stands. Locate the black tube coming out of the firewall near the centre. Using a coat hanger insert into tube until there is resistance the wiggle back and forth until water starts to drip. On the inside of the passenger footwell remove the under dash cover remove the bolts on the blower motor and disconnect the wiring replace the blower motor and reinstall.

Follow the lower radiator hose on the back of the motor. It is in front of the water pump.

I would check the windshield seal, and the drains for the heat/ac system. If those drains are clogged water will come in through the cowl vents and collect in the system until it overflows onto the carpet.From the Blower motor question below...Recall and Technical Service BulletinThe body style that ran from about '99-'03 had a issue with rain water getting into the blower case and ruining the blower resister assembly and the blower motor. There is a modified cowl cover that is supposed correct this condition. One tell tale sign that you have this problem is pull the blower resister assembly out and examine it. If it has corrosion or rust on the terminals, you have this problem. Replace the resister assembly, blower motor, and cowl cover.

Blower motor not working: could be the electric motor, or A fuse, or A short. Blower motor working: could be low engine coolant, or A stoped up heater core, or loss of vacumme to the inside of the car from the engine, or A bad water pump, or A bad thermostat.

Clear the condensate drain that is under the vehicle. It should be somewhere near the passanger side, near the firewall. If the blower is not on at all on some speeds, but works on others, then the blower motor resistor is probably your culprit. If the air is still blowing, but feels reduced when the condensation is built up, then it is probably just being bogged down by water accumulating in the blower motor. Try clearing out the drain and checking the blower when all of the water has been removed; this should help you diagnose the blower problem better.

If it has corrosion or rust on the terminals, you have this problem. Replace the resister assembly, blower motor, and cowl cover. There is a detailed posting on this problem in the "Related Links" below It's very easy. You'll see the round, black blower motor on the right side of the passenger side of the car, under the glove compartment. Either remove the glove compartment door by taking out the three screws under the door itself (very easy) or gently push in the two retaining bars on either side of the glove box door and let the door drop down. I think removing the door is easier and more efficient. There are three screws holding the motor in place. They are very obvious. Simply remove them (I think they are 9/32nd socket heads). Disconnect the wiring clip going to the motor (easy and pretty obvious). Then pull the motor out. It may feel like it's still attached, but if you took out all three screws, just a little pressure will get it out. You may have to remove one of the plastic one-way fasteners holding the plastic piece under the glove box in order to get the motor out. I had to do this. Gently, but firmly pull the plastic piece until the plastic fastener comes out of it's hole. Or you can snip the fastener shaft. You'll have to replace the fastener if you do this. Then just reverse everything and your motor is back in place. Answer Look under the passenger's side dash, just below the glove box area. There may be a plastic shield underneath, that you remove by simply tugging down on it. On the heater box, you will see the blower motor held in with four 8mm hex head screws. Disconnect the electrical connector, remove the screws, remove, and replace the blower motor. It should take you about 15 minutes. It's pretty simple. The blower motor is under right-hand side of the dash, remove panel to see it. If you want got to mechanixtrix.com they have pictures of it and how to remove it. Also check cowl panel on right-hand side it may be warped allowing water to enter and causing blower motor to break. 1. Disconnect the negative battery terminal. 2. Disengage the instrument panel insulator from the instrument panel 3. Detach the wiring connector at the blower motor. 4. Remove the 3 screws retaining the blower motor to the evaporator housing and remove the blower motor and wheel assembly. 5. If required, separate the blower motor wheel form the blower motor by removing the retainer from the blower motor shaft and sliding the blower motor wheel off the blower motor shaft. Reverse to install. I have the same problem with my 1989. I had to take the glove box out to get to it. But before you purchase the actual blower motor, take a tester to the wiring that goes to it (starting at the blower motor end and make sure its not one of the coiled looking "resistors" along the way or the switch) Turned out on mine that its not the blower motor itself, but something in the switch or the path of wiring to the blower motor. Sorry not more help. Cathy The blower motor is located in the a/c evaporator housing on the passengers side under the dash. Remove the cover from under the glove compartment on passenger side. Once removed the blower motor is towards the passenger door. Unplug the blower motor and remove the 3 screws from the housing. Pull the motor out and reverse order of removal. Some brand new motors don't come with the fan, so you might have to take old fan off from old motor and reattach to new motor. Is very simple just be careful when taking clip off of shaft holding the fan on. Chck behind the glove box area

The 2UZ-FE motor does not have a timing chain but a timing belt and it should be changed between 90k and 100k miles along with the water pump.

Thermostat may be stuck open. Drain the system, replace the thermostat and fill with a 50/50 mix of the correct antifreeze and distilled water. Heater core may be clogged. Replace the heater core. Blend door be stuck. Blower motor may not be running. Repair the problem. Blower motor not working. Either the blower motor is defective, fuse is blown, or the resistor pace is defective.

If your 1995 Oldsmobile Aurora keeps overheating and the issue is not the thermostat or the water pump, it could be the cooling fan. It might also be the radiator (leaking) or the hoses between the engine and radiator, or the shroud could be clogged or damaged.

The thermostat is inside of the water inlet on top of the motor. Disconnect the top water hose, then unbolt the water inlet. The thermostat can then be changed.

I HAD THE SAME PROBLEM WITH WATER LEAKING IN ON THE PASSANGER SIDE. THERE IS A RUBBER SEAL TO STOP THE WATER FROM GOING DOWN INTO THE HEATER. IT WAS OFF THE METAL RIM UNDERNEATH THE PLASTIC STRIP/COVER BETWEEN THE WINDSHIELD AND THE WIPER. REMOVE THIS COVER AND REPAIR THE RUBBER SEAL FIRST, THEN REMOVE THE FAN/HEATER MOTOR AND TEST TO SEE IF IT IS WORKING , IF IT IS THEN THE RESISTOR IS THE PROBLEM. I HAD TO REPLACE BOTH THE RESISTOR AND THE MOTOR ON MY IMPALA.

No heat can be a clogged heater core or a thermostat stuck open. No low speed blower motor is a defective Blower Motor Resistor Pack. I suggest you drain and flush the cooling system with the heater set at hot. Replace the thermostat with the correct temp unit, pour in a 50/50 mix of antifreeze and distilled water, and bleed all air from the system.

had new blower motor installed in my 2006 gmc now waater is leaking inside car when ac is on

The A/C drain plug is clogged. When it rains the humidity is high and the A/C will remove the moisture in the air. If the drain is plugged water flows to the passenger side through the blower motor and onto the floor have the drain plug cleared or you will be replacing your blower motor on a regular basis. Until then do not use A/C or front defrost setting.
