STUMPED! Heater Click - Braking Click
So the other day I noticed a small clicking noise originating from the passenger side front/dash area. I thought it was my brakes because while braking the clicking would get louder. So, I decided to change my brakes because of this, and sure enough that wasn't the problem.
What I discovered today was the clicking only happens when I have my heater on. The clicking now happens all the time either while in drive or parked as long as I have my blower on 1. If I turn up the blower to 2, 3, or 4 the click doesn't get any louder. But while braking with the heater on 1 the clicking noise grows much louder. Any help would be helpful! Thanks! Oh yeah 2008 Malibu LS 48,000 miles.

Re: STUMPED! Heater Click - Braking Click
does the ticking noise frequency increase with fan speed? sometimes the blower bearings get dry and tick at slow speed.
listen by the blower motor with a mechanic's stethoscope. If its from the blower; remove and inspect and run while its removed from the hvac case. Make sure something hasn't fallen into it or a rodent isn't building a nest.

No the frequency doesn't increase with can speed. I don't have a stethoscope and to be honest I wouldn't know what I was listening for anyway. I was hoping something easy, but it sounds like it's going to be tough.

It's possible something ( ie - paper , etc. ) has been placed on the dash and it fell down and has become lodged in the defroster vents . Have you checked them ?

No. I religiously don't place stuff on the dash, because it causes distraction for me. The crazy thing is I didn't hear it yesterday while driving.

Could be leaves or leaf stem came in from the bottom of the windshield. Takes a while sometimes for them to work their way into the squirrel cage.
