The fuses on top of the battery are a big 40 amp and one of the small 30 amps. If that doesn''t fix it go to http://alldatadiy.com or get a chilton''s manual and it will tell you how to diagnose the problem. _____________________________ 2000 2.0 Jetta ECS Underdrive Pulleys ECS Intake ECS FPR ECS Stage 1 Clutch Nology Hotwires Autotech Oil Cooler Borla Cat Back Magnaflow Cat (in reply to tgrill26) Post #: 2 RE: Coolant Light/Air Conditioning/High Temp - 8/21/2008 10:21:01 AM    tgrill26   Posts: 2 Joined: 8/21/2008 Status: offline Thanks I will check those fuses!

My temp light is flashing but only every once and a while. My check engine light is staying on but dont really know why. Also My AC is just blowing out straight hot air and its like my ac doesnt want to accept the coolant. I had Auto zone run some test  on it and it flashed 4 different codes, 1) Temp gage or vaccum leak and the rest were O2 Sensors!! I know how to fix the basic things on my car, but I dont understand why my temp gage is flashing.
