A while ago the cooling fan would cut in and out every second or so and I could hear the relay clicking. I replaced the relay and it worked fine for a year or so. Now the fan is cutting in and out again but the relay doesnt click like it did before. Would there be a sensor that I can check? Or would I buy another relay at $50.00 a shot? :nono:

Is this the primary fan, or the aux? Is the A/C compressor cycling with it?

Sometimes a low A/C charge will cause short cycling of the compressor, and the aux cooling fan.
