Hi everyone, I have 1989 Chevy ck3500,454, manual stick with 85k miles on it. It has a factory auxiliary fan designed to come on when the engine coolant reaches a certain temperature. My problem is it's 70 degrees outside and the fan is constantly cycling off & on at idle or any other speed when it shouldn't be on at all. It may stay on for a minute, then off for a minute. I've been reading about a fan switch, is this what I am looking for to fix it & if so where is it located, thanks for any help, much appreciated.
have the same problem?
