Hey guys, I did a search, and was unlucky in finding anything that helped me, so I am hoping someone here has had this problem, and found the fix to help me out. I love my AC blowing cold air, but it gets to a point when it is getting past my comfort level, and I want to drop fan speed a little.

1991 pickup with AC. I have only one fan speed, and it is high only. What is the fix, and any and all details on fixing it would be appriciated. Thank you in advance.

 

Turn the temp switch down ?


Turn the vents away from you a bit..?

 

Yeah, I do that, but makes for a real pain int ha arse all the time doing that, and I like my stuff to work the way it is suppose to work. Correctly!

 

blowe motor resister, found on the passenger side, just under the dash behind the glove box

it's got one plug-in, holds in with 2 screws:




my 91 had the same issue when I first got it. $45 later from the dealership, all my fans speeds work now

 

Cool, thanks for the help bleeder. by the way, I havent posted on your rebuild thread yet, but great work, and very enjoyable!

 

Ditto on the resistor.

Resistors are designed to allow only the high function when they fail. As the resistor's job is to route the current through another path to limit the amount of power going to the fan.

I dont know if that makes sense. I cant explain it any better. lol
