Hey all! I’m new here, and newly the owner of a 1994 S10 2.2L with the 5 speed std trans. I picked her up for a great price, runs and drives, at 234k miles. It needs maintenance (tires and brakes) and the only other ‘serious’ issue is the air conditioning doesn’t work. However I’m hoping I’ll get lucky here; the dial that should click between different settings (ac/defrost/vents) seems to be broken... it doesn’t ‘click’ but rather spins around and around and the unit only blows defrost. I’m not familiar with how the controls work, but I’m hoping that if the dial can be replaced or repaired that I will once again be able to select different settings, one of which would be A/C. Is that how that works? Or, would I be getting cold air as-is with the defrost on and the temperature selector set to cold, if the ac system was working? Do y’all know, and if so, how hard is it to repair that? Thanks so much!
