Re: over heating
does the car overheat when you are driving at highway speeds or does it overheat when you are driving slow or stopped? Is the coolant topped off, have you been losing coolant?

Re: over heating
You need a schematic and see whats on that circuit. Then start to check and see why your fans dont kick on..If you checked the fuse.. you could also try and swapping out the fan relay for a known good relay..but definetly get a schematic/wiring diagram

Do your power mirrors work? No, I'm not kidding.

Re: over heating
Only the rad fan, [right side fan] comes on, [at about 200 degrees F] for engine cooling, both thew rad and condensor fan turn on for AC.

To test check the greounds for each fan, [black leads] should have full continuity to chassis ground.

Test the fans by jumping the rad fan relay and the condensor fan relay, rad fan fuse is fuse 33 - 20A and condensor fan fuse is fuse 35 -20A, [both are hot at all times] in engine bay fuse box, [test fuses while still plugged into fuse box].94
