so a few days ago my 91 Z started this cute little thing where the gauge cluster goes completely dead(except for the gas gauge). then randomly I will crank it up and everything will work fine. then another time I will crank it up and nothing again. seems to be no pattern to it, no blown fuses, I even pulled the gauge cluster out of the dash and checked allthe connections, looked for any signs of corrosion ect. even completely disconnected it, then reconnected it. made no difference. and the same time it started this, my a/c has stopped blowing cold, and I can't hear the compressor cycling. everything else on the car is working fine. it starts right up, all lights work, radio, everything else electrical is fine. this is cinfusing the hell out of me and I have tried searching several times and havent come up with anything helpful. anyone experienced anything like this before or know what may cause it? it n/a also if that makes a difference
