Radiator Fans Come on at ON position - even cold engine
I recently purchased a 96 Camry LE and I am having engine overheating problems, on the highway. One of the strange things I have noticed is that even when the car is parked inside the Garage for a whole day (cold engine), when the Key is put at the "ON" position without the A/C on or without starting the engine, both radiator fans will come on.
What could be the problem? I feel this particular problem should be an easy fix, although I've probably got other problems since the engine does over heat when driving for 15-20 min on the highway @70mph. It will not overheat while driving around town.
I took it to a shop where they did a leak test and apparently found no leaks. What should I get checked next, without breaking $$?
