Heater blower won't cut off, even with ignition turned off

Car is a 1992 Buick Lesabre with comfort control. Has worked fine until yesterday. Now when I cut the ignition off, the blower still runs on the heater. It stopped after 3 hrs yesterday, but today it completely drained the battery.

    Heater fan stays on when vehicle is off. While driving the vehicle

    the blower can be set to different levels of air output from low to high

    but the amout of air output remains the same. Had to pull the fuse

    to keep battery from draining. 2006 silverado limited edition.

My 92 Le saber did that and we changed resisters and did a number of things and nothing worked Finally my mechanic put a bypass switch some where on the power line and after that it worked. Sorry I am not sure where but after he put a cut off switch in the line everything worked again.I don't own that car anymore so I can't even follow up to see where it went.

92 Buick LeSabre Blower Door Closes after 15-20 minutes


I'm fairly sure that model still uses a vac control for the hvac. You may have a vac leak in one of the lines, the main controller, or one of the blend doors. The blend doors are under the dash and may be difficult to reach.

Heater fan motor burnt up. Replaced it but when the 30 amp fuse is put in the fan wont stop even with the key off


You need to replace the blower control module. It is close to the blower motor in the heater case $$$ you might try to get a used one.

I have 1992 buick lesabre with a heater fan that wont turn off


the heater fan relay should be in the fuse panel. if not ck see if there is a regular fuse too. Who was messing with the car to do that? find the heater blower switch which should be by the radio... and sometimes it is easier to just take out the radio to get more room. check the wiring make sure nothing else is hooked to it . do the same for the blower which may be easy to get to under the pass side dash or thrught the glove box. but check the wires.

1992 Buick Lesabre - heater won't cut off, even with ignition off


There has to be a positive wire making contact with the blower wiring. And if it still runs while the car is off, then it could only be a handfull that have power while the car is off. Like the cigarette lighter wiring, headlight switch wiring, curtesy lighting, hazards. Can also be under the hood, hood light ( if you have one) whether or not it works. I sincerely hope that this could be of some help to you. Good luck and best wishes.

Cruse control


Does your blower fan work on your heater/ac or your rear defrost work it could be the igniton switch were you put the key in. Turn the car on and off several times once you notice the cruise will not work and see if it starts to work if it does than it is the ignition switch this just happen to my 2003 century.
