AC fan only runs on high???

Postby DocGlenn » Sun Jul 08, 2018 9:32 am

I’m having an issue with my AC fan on my 1990 GTR. It only runs on the high speed in auto or manual mode. I replaced the fan controller behind the glove box, and thought that would fix it, but no luck. Still doing the same thing. Does anyone have any suggestions on what I should try next? Thanks!

On many vehicles, the cause of this is a bad blower motor resistor

That's the part that I replaced. I called it the fan controller, but it actually is the resistor. Unfortunately, that did not solve the problem. Hoping that someone might have another solution. replacing the climate control unit might be next, but that is expensive. Anyone with a suggestion, let me know. Thanks!
