I've noticed this since the first day I drove my truck off the lot. When I'm running my air/heat I hear this clicking noise under my truck somewhere that loops every 5-10 minutes while running the A/C...

Any ideas? Anyone else is experience this?

My buddy's ranger does it too and I'm just curious to see if it's fixable or known.

 

More than likely that is your A/C clutch cycling on and off. That is normal.

 

^^x2! It's perfectly normal.....most likely what your hearing is the a/c clutch kicking on and off. You'll also notice an rpm change when your at idle.

 

i was just noticing this in my truck also. Doesn't seem normal, but glad i know what it is now

 

Awesome, thanks for the info!
