if the fan is working properly, it wouldnt be the temp sensor....if the sensor was bad the fan would either never be on and the car would run rich thinking its too cold, or it would always be on
my heat takes like 10-15 minutes to get warm i think its the thermostat. what do you guys think?
If your thermostat is stuck open it will take a lot longer for your car to warm up. I had one stick open in -20 degree weather. Even after a half an hour I was still scraping ice off the inside of the windshield. It was so cold in the car I pulled off the road and stayed in a hotel until a shop opened up the next day. (Why does this stuff alway happen on a cross country trip on Sunday?)
Thanks for all the responses. I've replaced the thermostat. Flushed the radiator. Fan is working. My next guess would be the water pump. Just a leap here, but would the heater core have anything to do with my problem? Again, just a leap.
