First post here, thanks in advance. I have to issues I need to solve: 1-Cabin Air Filter- Where is it located? I bought a filter and want to change it. 2-My overhead/rear heat/AC controls no longer work. Should I first check fuses? 3-My factory radio from the get go always makes this wierd noise that comes and goes. Even had it replaced w/ a new on under warranty, but still happens. Kind of sounds like an electronic interference or something. Of course it never occurs at the dealer. I'm almost ready to just put a aftermarket one in...

Replying to: platzie (Nov 01, 2006 5:45 am) Is the sound you hear a high pitch 'whistling' sound that slightly changes pitch with change in engine speed? If it is you could have an intake manifold gasket leak. That makes the same kind of sound as sometimes radio does when the alternator interferes with it. If your problem is electrical, not the intake air leak you might want to work with your alternator, not the radio to fix it. Amazing if the dealer replaced your radio on warranty and did not go check the alternator? Arrie

Replying to: platzie (Nov 01, 2006 12:52 pm) Why replace the radio when you have this sound when radio is not even on? Perhaps my 'whistling' was a bad reference for the type of sound. Transistor sound is a good reference to what I mean by the type of sound it can make when intake manifold gasket does not hold against the vacuum. Just for the heck of it have your intake manifold fastening bolts checked for proper torque (or do this easy task yourself). That at least rules it out as a possible source for the noise. And don't be surprised if it even fixes the problem. Arrie

Replying to: platzie (Nov 01, 2006 5:45 am) Found this thread because my overhead controls work, but the dash controls don't provide heat... only cool. I know it's the "gate" or "valve" that mixes air, I just need to locate the fix. |

My burb started making this belt flapping noise and I isolated it to the A/C. It is not consistent but intermitent. The noise quits when you turn off the A/C. I asked around and was told it was probably the belt tensioner so I replaced it with no improvement. The A/C works great (we live in Texas). Anyone ever had this problem or know what I should check next?

My 04 Tahoe climate control on dash blows cold air. When I turn the knobsfrom 60-89, it blows cool air but when I turn it to 90 degrees, it blows warm air. The controls on the ceiling work for blowing warm and cool air in the back of the vehicle. Would you think that a temperature sensor for the climate control in the dash is bad? Thank you.
