popped the hood with the car running to check atf level and I could hear a clicking sound every 5 or 6 seconds. put a light on the compressor and it would not be engaged and then it would engage and click. didn't have the ac running or anything, in this cold weather you kidding?
I did have the heater on though, blowing through the upper and lower vents. I turned off the heater and the compressor stopped engaging, no more clicking noise. I tried turning the heater to the position that only blows warm air from the floor vents, no more clicking. What is the deal here?
The car is a 96 Ford Taurus but I don't know if that matters. No, I didn't have it on defrost or anything. It's hard to hear the clicking unless you're outside the car so I am not sure if it's been doing this all winter or what. Is this normal? Every 5 or 6 seconds? What would be the purpose of that?
