the heater blower fan is in the heater housing assembly on the passenger side. You need to take out the whole housing assembly in order to access the blower.
you could have anything from a fuse to a blower motor problem ,,the blower moter is under the wiper assembly ,,, remove the assembly by removeing the 10 mill bolts ,,, and the plastic cover on the blowermotor houseing is held on with clips ,,, also check the blower resistor module which is in the blower housing
Not sure about the relay, but there is a blower resistor assembly located on the heater case to the right of the blower motor.
The blower resistor assembly is located under the hood, on the heater case to the right of the blower motor. Haynes Manual #36071
The heater blower/motor seems to be incased in a plastic housing on the passenger side firewall , right behind the on-board computer. There are 3 screws holding the computer in place and need to be removed, to access the heater/blower motor behind it. The plastic casing needs to be cut with a utility knife to access the blower itself.
You can access it by removing the three screws which retain the glove box and then remove the glove box itself. You then remove the duct between the blower motor assembly and the heater assembly.
Possible options: * blower motor * electrical connection * switch assembly * resistor assembly * fuse There may be other possibilities but that's all I can think of at the moment.
I am answering my own question. Just did this over the weekend. Take out the glove box. Take out the kick panel. Disconnect blower harness(the one with the orange wire)from the front, not the motor side! Remove vaccum line. Remove bolt holding blower assembly to frame (near top of dash). Remove two bolts holding blower assembly to heater core assembly. Remember how everything fits for reassembly. Slide blower assembly down. Take assembly off the car and unbolt blower motor. Reverse to assemble. someone in the future. Thanks for the info. I'm going to be removing my heater blower this weekend.
Drain the engine cooling system into a clean container for reuse............Remove or disconnect the following...........Negative battery cable Heater hoses from the heater core Instrument panel storage compartment Electrical connectors, as necessary, that may be in the way Center floor air distribution duct Hinge pillar trim kick panels Blower motor cover screws and the cover Blower motor screws and the blower motor Steering wheel and the steering column Instrument panel fasteners and pull the instrument panel back far enough to gain access to the heater assembly Screw located on the interior side near the evaporator pipe, if equipped, while holding the heater assembly against the firewall 4 heater assembly-to-chassis screws and the 2 heater assembly-to-chassis nuts, working in the engine compartment7 heater cover-to-heater assembly screws and the cover Heater core from the heater assembly
The blower resistor assembly is located on the heater case to the right of the blower motor. The blower motor is located under the hood on the passenger side firewall.
Blower motor resistor assembly is located under dash on passenger side.
Disconnect the negative battery cable, heater blower resistor wires and blower wires. Disconnect the heater core ground strap at the dash panel.Drain the cooling system and then disconnect both heater hoses at the heater.Remove the seven screws attaching the heater/blower case to the plenum and remove the heater/blower base.Remove the four screws from the heater core shroud, and then remove the shroud and core assembly.Separate the core from the shroud by removing the three screws and core mounting clamps and then separating the two.
Remove the wiring harness from the back of your 2005 Chevy Cavalier heater blower motor. Remove the heater blower motor retaining bolts. Remove the heater blower fan.
The blower resistor assembly is located on the heater case to the right of the blower motor. - Haynes Repair Manual #36071, 1993-2005 Ford Ranger Pick-ups
To locate the blower control resistor, windshield wiper then plastic panels under windshield wiper must be removed. Then remove wiper motor and linkage assembly. In the center of the car under the wiper linkage the plastice heater motor cover must be removed. Remove heater motor. The resistor/controller mounts directly below the heater motor. Resistor unit and wire harness must be removed as an assembly. Install new resistor and work back through directions. Due to the amount of labor involved it is recommended to check the blower motor at the same time.
The blower is mounted just above the passenger's toes, next to the right hand side of the car, under the dash. Disconnect the electrical connector. Remove the three bolts (vertical) that hold the blower motor up into the blower housing, and the motor will come straight down into your hand with the impeller attached.
Heater blower resistor is what controls the low medium high speeds...
Check the blower motor electric wiring connector assembly for corrosion, if OK , remove the resistor assembly and check for corrosion. If the heater core has rupture there will be some coolant getting into the assembly which over time will corrode the assembly. Te connector itself could be so badly corroded that the power has been interrupted and the possibility of fire or melting of the connector is there. I had to purchase a new connector and resistor assembly and splice the connector to remaining wiring. Hope it helps.
You probably have water tht has entered the heater case through the cowl air inlet, which has damaged the heater blower resister assembly. It is held into the case with two 8mm screws, and is locatted under the glove box area right beside the heater blower motor. Turn on the blower and follow the sound, and you will find the resister assembly right there. I'll bet if you replace the resister assembly, you will have all your speeds back again.
The blower may simply have burned out. If the blower is out then the heater probably still works.
Remove the wiring harness to the heater blower fan. Remove the retaining bolts. Remove the fan from the blower. Reverse the process to install the new heater blower fan.
you have a bad heater blower motor or something stuck in blower cage
It is encased in a plastic housing on the passenger side near the firewall. Look for a line to cut out with a utility knife. Usually it is somewhat brittle and may come off in pieces. Once this is out of the way you can access the blower and mounting screws. After the replacement blower is installed there is no need to replace the plastic housing.
The heater blower switch and the electrical plug attached to it may be at fault. Remove the heater control unit from the dash and inspect the plastic electrical plug attached to the blower switch, you may see it has melted. The switch and plug is available from your local auto parts store.
