Air not shutting off when I turn the car off

It keeps blowing full blast. I have to turn the car back on and turn it off and wait a few seconds. Any idea what could be causing this? I think the 100+ degree temperatures are making my car go a little crazy.

Hmm. Well, I always shut mine off before I turn off the ignition. That would be one solution, but of course doesn't fix whatever the issue really is.

Thats happened to me a few times in my 95.I did nothing to fix it,I did not look for a problem,it just stopped doing it .good enough for me.I pondered,lit a few candles and it hasnt repeated.

Blower Control Module in back of the glove box

Oddly enough my car seems to fix 99% of the issues on it's own. I'll give it a few days before I go searching. Thinking it may be something with the contacts on the blower but I'm not sure.

blower control module...easy fix...you're isn't 100% out, but sure seems like it's on the way

Thanks guys. Was coming back to post an update thinking it was the BCM myself. It's gotten worse and seems to be possessed. It randomly turns up and down and sometimes turns up when I hit the throttle and down when I brake.

The weird thing is that my blower motor is making weird noises when I turn sharp left? It's almost like squealing, very weird! Gonna pick up a new control module and see what happens. Might need a new blower motor as well but not sure.

So all I'm seeing is a blower motor resister than is an unbelievable $151 from the local store. Is that correct?!

Because it's not a resistor although that is what it is indexed as many placed. It's part of the automatic temp control version of the HVAC. The similar device is similar price across many GM cars. If you look at the listing for the same year (1997) Buick Regal you'll see the resistor for the non-auto-temp cars and the module for the auto-temp cars.

I was actually looking at one off of a cadillac that appears to have the same mounting and plugs. It's 1/3rd of the price. I'm going to see if it will work.
