Want to fix the problem, figured it was a temp sender. Bought one and cannot locate the sensor on the motor. Ford tech said I was crazy, guess he is to since he could not locate it either. When the temp gauge pegs out, the a/c shuts down. It only pegs out when I am driving....Cools down at the redlight. When it shows its overheating, I can shut the motor off wait 5 seconds and turn it back on and the temp gauge is showing normal!
