Question:

I have a 1997 Explorer XLT and whenever the AC or heater is on at all there are random fairly loud clicks that come from somewhere in the engine. Is this normal? AC cold and heater warm, but the clicks are annoying. Thanks for your input. PS: I have had the AC recharged and fixed twice a while ago it was putting out warm air. Dont know if that matters. – Justin

It’s probably the compressor clutch clicking on and off.

Response:

Is that normal, its often, maybe at least once per minute. – Justin

If it’s cycling that often, you might want to have the pressure checked; you could be low on freon. Or, the temps may just be moderate wher eyou are.
