I have a factory air car, the ac control has 2 knobs broke off. Can the knob and lever be swapped out of the assembly? If so, does anybody have a source for these? I found one with 1 broke and a rough faceplate, but not sure if I could swap just the the knob and lever, asso the one broke in it is one of the same as mine, didn't know if they were all different. I have plans to send it to hot rod air for them to rework to control their evap kit, but they said they could not help with the broken knobs.

Its a little difficult to answer without a pic. But I tried fixing a broken lever on mine. I gave up. Look on e-bay. Theres usually some controllers for sale there quite often. Or check out this link.

They have lever repair items there. I Hope this helps.

Thanks, I ordered from them, just what I needed, $48 for all 3 new levers, and knobs shipped. Just for anyone else that might be wondering, looks like all 3 are the same.
