Hi guys, I just picked up a 76 corona wagon a couple weeks ago. Got the fuel pump swapped and some other tune up stuff finished and she is running strong. Now I'm looking at the a/c system. My question is, and this may sound incredibly stupid, how do I turn the fan on? The a/c and vent controls are on the dash but I don't see any mechanism for actually turning the fan off/on. I have seen pics online of other year coronas that had a knob next to the cigarette lighter to turn the fan on, but I just have a cigarette lighter in that panel. If anyone can enlighten me that would be awesome! I can post pics tonight if that would help.
