Annoying Click Coming From Behind Heating/Cooling Controls When A/C Is On...
I noticed this back in the fall when it was warmer and was running the A/C but forgot about it over these colder months. What it is is just a loud click that comes from somewhere in the dash behind the cooling controls every 7-10 seconds while the A/C is on. What is this from? It's like it's sending a signal to the compressor to cut it off and on way too frequently, but I'm not even sure if anything is even happening when the click occurs.
It's not a huge deal but clicks, rattles, and other noises in my vehicles that others don't notice drive me crazy. In this case it's not too loud...I can't hear it when listening to the radio at my typical volume level... but it's easily heard at cruising speed with the volume really low so it is significant to overcome a little audio as well as cabin noise.
So am I just weird and this is typical or what? I'm guessing it's just me.
BTW: 2005 Silverado with the 5.3L and Dual Climate Control (all silverados have this though right?)
