When I first bought my car about 9 months ago speed 4 didnt work but magically started working over the winter.

Two weeks ago I had my ac on full and went to shut it off, the switch seemed hard to turn and all the fan speeds stopped working. I kept going to each speed and finally 1 worked, and then 2. That's all that will work now.

Not sure if it's the switch itself, a fuse, or something completely different. Any ideas?

 

I'd suggest getting an HVAC controller from the classifieds section. Sounds like that's what's going.

 

Okay, the one I have also has burnt out bulbs and planned on switching them to led. So I'll just try that.

 

right id figure out the issue with them not working before u go LED. i mean plan do it together but make sure its working before u pull out the soldering iorn

 

Remove switch. They brake easily over time. Use pliers to control fan speed..if it don't work replace the ac control uniit.... Shouldn't b expensive

 

Well the switch 'clicks' when I turn it and everything feels like its moving so Im not sure if it's that.

 

Probably the resistor.
