My 2003 has a ticking sound like that of a clock pendulum that recently started as well. I have been searching high and low to find its origin. I know it sounds like it's in the dash somewhere but am having a very hard time finding it. HELP please.

I found that the issue of whistling came from the hands free phone/onstar mic above head. On mine, there was a ground loop that was found ultimately to be caused by a poorly grounded negative battery cable(to the engine) and loose/stripped negative battery pole bolts.

I have a 02 Denali. The only problem I have had in my 93xxx miles is that the seat heaters no longer work (any of them).

Hi! Love my truck but just ran into a problem today. I have electric running boards. I left the lights on this afternoon and drained the battery. When I got things going again, the running boards do not operate. (In fact the the passenger side runnig board is stuck in the extended position and the driver's side running board is in the retracted position). The fuse is okay yet the button on the center consloe doesn't do anything. Any ideas??

Steering Wheel Vibration by jallard

Have a new 2008 Denali w/the 20 inch wheels. As soon I got on the highway noticed a vibration in the steering wheel starting at 55 and getting worse as speed increased. Especially annoying after 65mph. Steering wheel shakes and passengers can feel it. Had 2 front wheels balanced but did not fix the issue. Then had all 4 tires balanced an again did not fix the issue. Now have 2000 miles and am ready to take to dealer but am not looking forward to it. Any idea what may be causing this? Bad rotors, bad shocks, suspension, etc. Is it a known problem that others are having? Any info would help me so when I do take it to dealer I can speak intelligently!

Tire Pressure by jallard

Have a new 2008 Denali with 20 inch rims. On the door jam, it says to inflate tires to 32 psi for this size. On tires it says 40psi. Which is correct. I was told 40 psi so the tires wouldn't cup. Am confused. Wondering if over inflating by 8 psi per tire can cause tire vibration.

40 is probably the maximum psi for the tire. That doesn't mean you should set it to 40, it just means that's the most it could handle. I typically go with the door jamb recommendation, plus 2-3 psi for slightly better mpg (lower rolling resistance at higher psi). It results in a slightly firmer ride, but still very acceptable. Perhaps slight cupping will result, but I haven't had any problems with that in any of my last four vehicles. I have 17"s, so you'll want to experiment for yourself with your 20"s. Set it to 32, and track your mileage for a month or so. Then go up to say 35 and see if you notice any deterioration in ride quality or significant increase in fuel economy.

Does the sticker on the door jam references the 32 psi with the 20" tire size? If it does, then the 32 psi is the minimum cold tire pressure you want to set at. I agree with ahightower to set the pressure a couple of psi higher than what's suggested on the sticker to gain a little on the mpg. Ultimately, you'll have to find your comfort zone by observing and adjusting the tire pressure you desire between 32 to less than 40 psi.

Please forgive me if this was too obvious a reply but it took a while, at least for me to learn this: for assuring that the rear doors unlock the keyless button is pressed twice. One press opens the driver's door. The second consecutive press on the button opens the remaining doors..... ....
