2010 Faint Ticking sound inside cab

[Mike940d]

I have a 2010 Silverado Ext Cab 5.3 that has a faint ticking sound coming from behind the dash at idle. The sound is very faint and you can only hear it while idling. Anyone else have any experience with this issue?

Have not heard that myself......does it go away or change in pitch when you rev the engine?

[Mike940d]

can only hear it when idling, if you rev the engine it drowns it out

Small exhaust leak or ticking AFM valve lifter?

I'm sorry to hear of the concerns you are having with a ticking sound when your truck is in idle. If you'd like, I can reach out to your dealership on your behalf to have this concern addressed. If I can be of any assistance please shoot me a PM here on the site with your VIN and mileage. I hope to hear from you soon!

Mine has the same noise, only when AC or heat was on. Comes and goes with mine, when i took it in slightly out of warranty, the est. was outrageous, said dash had to come out.

mine does it with AC/Heat On or Off
