I have a 1991 cressida, the air conditioning condensor fan and the electric cooling fan is not coming on. this causes the vehicle to overheat in summer traffic or during idle. I ran a jumper to the fan motors both work. I replaced the coolant sensor located in the thermostat housing, I checked the relay located in the fuse box in the engine compartment its ok. I dont think its a wiring problem. What else is there. Anybody else had this problem, is there another relay some where, could it be a faulty ECU. the car runs good, it has around 160,000 miles.
