I have a 2000 Camaro with the 3.8 V6. The A/C cooling fans were coming on at high speed when I turned on the A/C recently but now they are only running at low speed and the A/C isn't cooling as well as before. All the fuses are good, I've replaced all three relays, the compressor is running and full of freon. I'm wondering if this could be a problem with the engine coolant temperature sensor (ECT) and if so could anyone please tell me where it's located on this engine? Thanks.
