'91 GXE Manual A/C unit. It's been a while since this happened but i went to switch my fan speed up and i heard a snap and now the A/C (the light) only works on 1 and 2. There is a high speed, but i have to move my lever between 3 and 4 and hope it stays there. (it tends to fall towards 3 or 4) Does anyone know what could've caused this? Is it relatively easy to correct? Thanks.

 

proboly just need to replace the climate controls

 

not worth "fixing" go to a junkyard and pull one. I had to swap it out on my car. the part should be like 30 bucks and installing it is fairly easy.
