My electric fan wil not work. I tested the motor by jumping it and it ran fine. I guess my question is what fuses control it and what relay number is the fan relay? Tha air conditioner works fine after the engine heats up and the fan clutch kicks in. The ac blows hot air until then but works fine when driving down the road. Where is a good place to buy this part? Thanks, Carl

Check fuses 42 and 51 with an ohmeter for continuity. The fuses can look good but can be bad. The coolant fan control relay is relay 214 located behind the driver's side lower dash panel. When you turn the a/c switch to the on position with the car running, the relay should pick up. You can pull the relay and jumper 12v across the coil (85,86) and see if the contact (87,30) closes. If the relay is good then it could be the coolant temperature fan switch or the coolant fan contol module. The coolant fan thermal switch should be on the left lower side of the radiator on the lower coolant hose. The control module is located next to the blue vacuum reservoir on the front left side of engine compartment.
