And of course this noise only happens every now and then but when it does. wow is it annoying.
so of course when i finished cleaning out that area it didnt make any noises. which i figured that fixed the problem....but it didnt.
it continues again. and this sound shifts from driver side to passenger side. sometimes though.
so what should i do?
Already had the steering issue/bumping noise when you accelerate/decelerate. Thankfully, that was fixed under warranty.
Last year I had the problem where I had no heat the first cool spell. That ended up being another trip to the shop.
Just today I ran into the alignment problem/premature tire wire.
Thanks
Help!

We're sorry to hear that you're having some troubles with your HVAC system; what are your plans for getting this looked into?

I am into a month or so now. The knocking noise under my front passenger dash is scary especially traveling with young children. I spoke on the phone and via email with a GM customer service representative who recommended that I take the car for a diagnostic at Sport Chevy in Maryland-Bad Idea!. They diagnose the car as the REAR Actuator which I am unable to understand because the problem is when I switch from vent to AC that knocking sound gets louder. They wanted $405 to fix that problem but wouldn't discount it from the $113. diagnostic fee I had to pay. I am so frustrated because this is a very common problem with Chevys and for them to put it onto the power train warranty but not upheld their part of repairs is just ridiculous. An obvious problem. I took my car to a local shop and they will fix it for $200. And I found out that the car is leaking engine oil onto the transmission which I am told could caused a fire. GM would have plenty to worry about then. I am so disappointed and do not think I will every recommend or purchase another Chevy vehicle for that matter.
Disappointed at their customer service
