I fixed mine. Went to the local "U Pull It" junk yard. Scrounged around in GM cars looking for HVAC control heads and tore them apart looking for ones with same exact momentary push swithes. IIRC i think it was 2000 & up Monte Carlo I found it in. I then desoldered and replaced the switch. fixed 100%. replaced them dam buls too at same time, they have them at radio shack.
