Click sound under hood with Heater on
I believe I have a leaking heater core so I was checking for leaks by running the heater and sticking my head here and there around the Jeep.
In the engine compartment I noticed a constant click sound that would click about every 10 sec's.
Hum of engine, then CLICK
Hum, then CLICK
I turned off the heater to confirm, and the clicking stopped.
If it makes any difference, I think I had the vent setting on defrost.
Is this normal? Mith it be a vacumm diaphram opening and then letting loose?
