SOURCE: a/c & heater blower motor

Do you have a test light or voltmeter to do some testing? If you do find signs of heat then it's pretty likely that the switch has failed. If there is damage to the connector you can get a replacement from your dealer.

Either way, when you pull the ignition switch connector check for voltage on the pink/black wire. This comes from fuse 4 in the box. If you do have power here, turn the blower motor control knob to off. Install a jumper wire between the pink/black wire and the dark green wire in the ignition switch connector, right next to each other. With the jumper in place turn the blower motor on and it should work. If it does work this way then replace the ignition switch.


Removal & Installation

  1. Disconnect and isolate the battery negative cable.
  2. Disconnect the blower motor cooling tube from the nipple on the blower motor housing.
  3. Disengage the blower motor wire harness from the wire harness retainer.
  4. Unplug the blower motor wire harness connector from the HVAC housing wire harness.
  5. Remove the three screws that secure the blower motor and blower wheel assembly to the HVAC housing.
  6. Lower the blower motor and wheel assembly, and cover, from the HVAC housing.
  7. Remove the blower wheel retainer clip and remove the wheel from the blower motor shaft.
To install:

NOTE If installing the blower motor wheel only, press the blower wheel hub onto the blower motor shaft. Be sure the flat on the blower motor shaft is indexed to the flat on the inside of the blower wheel hub. Install the retainer clip over the blower wheel hub. The ears of the retainer clip must be indexed over the flats on the blower motor shaft and blower wheel hub.
  1. Be certain that the blower motor seal is installed on the blower motor housing.
  2. Install the blower motor and wheel assembly, and cover in the HVAC housing with three mounting screws. Tighten the mounting screws to 20 inch lbs. (2.2 Nm).
  3. Plug the blower motor wire harness connector into the HVAC housing wire harness.
  4. Install the blower motor wire harness into the wire harness retainer.
  5. Connect the blower motor cooling tube to the nipple on the blower motor housing.
  6. Connect the battery negative cable.
CAUTION On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in an accidental airbag deployment, possible personal injury or death.
NOTE The blower motor is located on the passenger side of the vehicle under the instrument panel. The blower motor can be removed from the vehicle without having to remove the HVAC housing.
  1. Disconnect and isolate the battery negative cable.
  2. Disconnect the wire harness connector from the blower motor.
  3. Remove the three screws that secure the blower motor to the HVAC housing.
  4. Remove the blower motor from the HVAC housing by rotating and tilting the blower motor as needed for clearance.

Heater has heat but not blowin air out


Sounds like a bad blower motor- first check to see if the blower motor free spins( with power off turn the motor with your hands if accessible or use a long flathead screwdriver) if it free spins replace the capacitor attached to its side- can pick them up in any HVAC supply house--WHEN REMOVING CAPACITOR BE CAREFUL -it is full of electricity and will shock you - use a screwdriver and touch both of the top connections at once- this de- energizes the capacitor- take it with you to the supply house to get replacement- then reattach new on and start up unit- if still no air flow look for obstruction- blocked vents- dirty air filter- crushed supply vent if under house or in attic- also see if the blower motor is operating if not may need a new motor.

Hot air through floor in 99 Suburban when blower is switched off


I the short answer is yes. The truck has a flow-thru vent feature as does most GM products. When the fan switch is off the outside air would flow into the truck.
I thought you could still direct the air by way of the control panel, but by the wiring diagram it looks like everything is disabled when the fan switch is in the off position.

Blower motor has a noise like a leaf is in the blade


It is very possible that the blower motor squirrel cage housing has leaves in it, they get in there from the air intake for the system at the base of the windshield. Remove the blower motor from the housing and clean out the leaves. These leaves also pose a fire hazard and I've seen that a few times, the heat source is the blower motor speed dropping resistor in the air duct near the blower motor squirrel cage housing, it can ignite the leaves, this can cause at the very least smoke coming out the vents, which can be a little exiting on the freeway.

The air conditioner isnt blowing hard


Do the blower speed settings still work, just weaker? Or is it just one low speed all the time? If you can still change the speeds then it's a weak blower motor. If its just one low speed all the time, (same speed for high and low blower speed settings) then you need a blower motor resistor.

How do i remove the fan wheels from my 92 accord heater motor?


Difficult to describe without pics, but…:
Once you’ve removed the glove box (I assume you’ve done this, and maybe you already have the motor out, in which case you can ignore most of this down to the underlining)
If the vehicle is equipped with air conditioning, remove the strap bolt (between the two nuts for the evaporator on the left and the two nuts for the blower housing (the housing is probably white) on the right, just a bit lower than those) then the blower under-cover and the three blower housing retaining nuts (two nuts at the top, already mentioned, and the nut at the bottom, which is roughly between the evaporator on the left and the blower housing cover on the right).
Pull the housing out far enough to unplug the electrical connectors (at the lower right edge, right above the kick panel) and remove the blower assembly housing.
If you’re replacing the blower motor itself, or either of the blower fan wheels, separate the two halves of the housing, remove the motor, remove the retaining clip(s) and remove the fan wheel(s). Easier said than done in may cases. The wheels, from heat and cold over many years, become very set on the blower rod. You'll have to work them off using whatever break-free lube you can find to do it, and a good deal of slight twisting, etc.
Installation is reverse. Then check for proper operation, before you put them back.
Hope this is at least helpful.

I just got the fixit for replacing a blower motor on a 91 accord, but I can't get the fan out because the AC box is in the way. Do I have to disconnect the AC to remove the fan box?
