In the winter I use the climate control with the fan and the air flow knobs both in the auto position, but the A/C button off. The fan used to delay coming on until engine started to warm up, around five minutes into driving. Now, the fan starts to run hard as soon as the car starts. Of course, the air is frigid. Any ideas? Thanks

Hello,

It sounds like you have a fan control relay that is stuck on. Remove the relay to see if it stops and if so here is how to test it to see if it is a trigger issue or the relay itself.

Let us know what happens and please upload pictures or videos of the problem.
