AC/heater fan on 1992 Buick LeSabre only works intermittently

\015 No rhyme or reason to why it doesn't work. The air is cool coming out of the vents, I just can't get the fan to work at times.\015 Posted / edited by AnonymousUser on : 15-01-2018

Answers :

Could be a bad control switch, relay or connection and ground at motor itself. Since it's intermittent, check voltages when it's working, then again when it's not. Wherever voltage stops, that's what you need to replace. Don't wait on this...when completely inoperative it gets much harder to find the problem!

I removed my blower fan resistor from my 1992 buick lesabre and the fan started working on high speed only now won't work again could I have burned something up by running the fan without the resistor

2005 LeSabre, with climate control. The A/C and Heat seem to work fine. However, the fan stop working yesterday. The display on the climate control panel shows the fan to be operating at max (led shows 4 bars), but no air. Located in San Antonio. The last 2 days have had large amount of rain (5-7 inches). I went through a lot of puddles and water, no high water. I pulled the fuse block cover (under the hood), could not determine which fuse to check. Same with block under rear seat. Car has 150,0

2004 Buick Rendezvous - Heater/AC fan switch shorting out. I had issues with the switch working on only 2 speeds. I then replaced the resistor block. I then got all speeds except 2. The AC Light came on with #2 but blower not working. Also, the AC and other 'directional' switch didn't work either only worked for a 10-30 seconds. I then pulled the dash and found the switch burnt on a couple of pins. I replaced the switch and control head BUT now the fuse keeps blowing the moment of going from 0 t

(1) The air conditioner / heater FAN on my 2003 Buick LeSabre does NOT run at all. However, for a few weeks the fan would shutoff for a little while; then, it would come back ON.

Also, when one of the air conditioner buttons is pressed, the clutch on the air conditioner's compressor DOES enagage. When the fan is running, the air conditioner / heater do their jo

Have a 1997 Buick LeSabre Limited with automatic climate control. The blower has stopped running. We checked the fuses (all OK). We did find a slight current however to the blower motor (about 2 volts at any setting and 0 when the engine is turned off) although there is no evidence that the fan is turning. I have read all of the postings in this site that may relate to this and wonder if it is a blower control module problem because, when it is that unit, the report is always of the fan

Hi, if all the fuses checked are o.k, there is a slight of about 2 volts to the blower when put on any settings and 0 volt when engine is turned off, then it is obvious that you have a faulty blower control module that fails to transmit the required ... 1993 GMC Sierra

2000 Buick Lesabre. I parked the car about 6 months ago because I bought a newer car. When I tried to start again the starter gets no power. There is an odd electrical problem because things like the vent fan, turn signals, head lights, tail lights all work fine, but other things like the electrical locks, electrical trunk release, electric windows, and electric locks do not work. I bought a new battery because the old one when checked would not take a charge, but the new battery still has the s

My 1993 buick lesabre is sending voltage to the heater/ac fan motor but no current. what's going on? we thought it was the fan motor, but the new one won't work either.

It helps to tell what a/s system you have, Dual Zone, or not. if the motor has voltage AND ground, it has to work, or its bad. The purple wire is power, the black is ground. If it is Dual Zone, the blower control module regulates blower speed, and co ... 1993 Buick LeSabre
