SOURCE: The heater / ac blower

It is the blower resister. I purchasted one at auto zone for $18.00. It is located under the passenger side dash. You need to remove the glove box and the plastic cover under the dash to expose the blower motor. the blower motor resister is right next to the motor. Simply unplug the resister remove the two screws and replace. I did this and now my fan works on all speeds.

SOURCE: 1992 cutlass ciera ac/heater blower

I can elaborate on this also. I have a 1992 Oldsmobile Ciera with 157k miles.

The blower motor had been losing it's bearings for a while and really lost them about a week ago. I bought a new blower motor; installed it (which can be done by loosening the power steering assembly by removing a couple lower bolts underneath the power steering resevoir. One is a "double hex bolt" which a nut, then 3 ground wires, then another hex head which will remove this bolt.) Also you need to remove a stabilizer bar the is connecting between the p/s pump and the rear cylinder head. Removing these bolts should allow the power steering assembly to be moved toward the front of the car, giving enough clearance to remove the blower motor.

We installed the new blower motor, tested it, it worked, but the relay started clicking like crazy. It was the second relay from the left on my car; you can tell which one is for the blower motor by lookign at the color of the wire going into the blower motor and looking beneath the relay panel for the same colored wire (on my car it was purple).

We put it all back together, went to test it again and it wasnt working. We then went and bought a new relay, which restored the blower to working condition. 2 minutes after we left again, it blew the relay. We then exchanged the obviously faulty blower motor, and purchased a new relay, and the car was restored to 100% functional.


In this person's case, it sounds like they just need a relay, but I just wanted to elaborate to help get this information more readily available. I feel like it would have helped me if I had it before I tried this repair. (which we got down to about a 15 minute job after the 3 times we had to do it)

1970 vw beetle windshield defroster no hot air


Does the heater blower motor work? If it does and the heater works, then the passage from the heater to the windshield must be not open. Real old-school, it is probably cable operated for defrost.
If the blower motor is not blowing air, it is an electrical problem with the motor. Would help to have a voltmeter. Do you?

Why does my a/c blower only work on high speed. switch works and resistor good and get power through it.


there is no resistor for high speed fan as it is full 12 volts
the slower speeds are resistor controlled
it should have a resistor pack in the blower housing ( air low to keep the resistors cool)

I have a 1993 olds cutlass ciera s and when i turn on the heater a/c fan it hardly blows air even on high


Check it the car has a cabin air filter... remove it vaccume out the air box carefuly and replace it. If you have a filter and you never replace it it is likly it is packed with what ever. are you sure the blower moter is working at all speeds? if not the blower motor resister is likly the cause. the resister is mounted on the blower box not sur on your car inside or out, if it is the problem then you should buy a harness kit too, because the ends ar most likly melted and not goning to be servicable.
