The other day I went to turn on my heat and nothing happened. I turned it up to 4 (max). I then found out that it will blow up untill 2 and then 3 and 4 don’t work. The actual heat works, its just the fan or wiring I’m guessing? Anyone have any ideas how to fix it? Its on an 89 240sx.
If you take off the glove box behind it you will see a plug, that controls the fan. I think its called a climate control switch?? i could be wrong on the name, but change that with a different one and your fan will work on all levels! Try to find somone with a parts car!
So you mean the little cubby box thing that goes in the middle, not my actual glovebox correct?
I don’t have the cubby or a deck in my car right now so that would make it easy 
No, I meant the actual Glove box! Once you take it off you will see the switch with a wire plugged into it, I believe it has 2 screws one on the top and bottom. I had the same problem on my 89 240sx.
Awesome, thanks! Now to find a parts car haha…
