I hope I'm in the right forum but I just bought a 92 Grand Am from my niece for $100. It has the 3300 eng. but has issues. I'll start with no brakes... none whatsoever and the ABS light is on?? Second the idle jumps up and down constantly but no eng. light. and third the fan don't work. Could it be the switch or the fan itself? The car is a SE and has 122K miles on it. My first priority is the brakes. Please help...
