GMC Yukon Denali QuestionsRefine by vehicle
2005 Yukon Denali 6.0. Check Engine Light comes on. "OBD code P0496. Evaporative Emission System High Purge Flow" . I have replaced Gas Cap. Can clear error but eventually comes back on.

The front end of my 2004 Yukon Denali was makeing noise. Took the Denali to a GMC dealer and they said it was the front differential. It has been replaced once before when it was under warranty. Now its no longer under warranty and needs to be replaced again.
I beleive my vehichle needs a recharge because the fan(a/c) comes on, but it's just hot air instead of cool.
I can't get the rear tire pressure light to go off. It's been serviced and they don't know why it stays on.

If I take off hard, stop suddenly (even from idle speeds) and if hit speed bumps faster than I should, I can usually hear some kind of noise from the rear of my vehicle. It sounds like metal on metal. Not a grinding sound or clanking, just a single sound (a single clank, maybe). Like if you were to hit the exhaust pipe with a tool while under your vehicle I guess is the easiest way to describe it.
I replaced the shocks, as I noticed the rear would sag a bit when taking off. But that didn't fix the problem.
Ive heard tons of suggestions, but its just people guessing off the top of their head. Has anyone had this before? Or any suggestions?

Last night the instrument cluster in my 2005 GMC Yukon Denali very quickly flashed "Service Stability" and then the message went away. Kinda freaked me out a bit as I was driving 70mph down the highway. What does that mean?
when starting truck engine light came on steady. dissconnected battery for 5 minutes. reconnected and light went out but now can not get any airflow out of center ducts. a/c works fine in rear. a/c does work in defrost and floor mode. so no heat or a/c out of front center ducts. checked a/c fuses seem fine. pulled out climate control head and pulled out wiring harnesses every looked fine. reinstalled and no change. help me please.
Had radiator replaced 5/25/2010. On 6/24/2010, heard ticking in engine. Took to shop. They said internal damage occured. Cost to replace V8-350 5.7L $6000. I put quart of Slick 50 in engine. Noise stopped. On 7/2/2010, temperature guage started to fluctuate and smell of burning antifreeze from engine. Found radiator empty. Refilled radiator and reserve. Drove venicle for 2 days refilling with water as needed. Vehicle drove fine to me. Couldnt find leak. Checked oil dip stick. Oil looks like milk chocolate. Back of oil cap looks like butter. I think it might be intake manifold gasket leak. The vehicle has 154000 miles on it. What do you think? Any additional thoughts would be appreciated.
my headlights stay on 100% of the time. when the green daytime light indicator is on, i cannot use my bright lights. the green indicator has a malfunction and stays on 90% of the time, even at night. how do you disconnect or override that to manually turn your lights on instead of the sensor regulating it?
The daytime headlights and the low beam headlights will not come on. I have checked all low beam and daylight running light fuses and relays in the under hood fuse box, and they are ok.
My 2001 Yukon Denali won't go into reverse, what can be wrong with it? Aproximately how much will repairs cost? Will you recommend a repair shop in my area? Thank you, Tam.
When I turn on the car, the information center turns on, the date is the default date. I can not reset it. After a second or two, it goes dark and then nothing.... What can I do?
After pulling battery to replace solvent reservoir, now driver side A/C blows cold as expected but now passenger side blows hot. Doesn't matter how controls are set either on pass side.
I pulled hot lead off battery for 5 mins and no change afterward.Checked all fuses too.
Need some pointers. Yukon 5.7 has 118,000 miles and has had it's share of electrial problems mostly with windows and tail lights. But now it's getting the gear out of neutral into 1st....how do I do that at home? We tried working on it Sun. but it turns on but don't budge! What did we forget to do or what did we do wrong? Anyone..? Advice please please please.or Am I better off getting a whole new transfer case?
after holding brake down the gear shift still won"t shift out of part without pumpping brake several times.
My right brake light and blinker went out first. then driver window went in and out, and eventually passenger window followed. now all windows dont work. if i try to roll up the windows the radio turns off and wipers dont work, and now none of those things work. ive tried fuses but that didnt help. maybe a short, if so how do i fix a short? also oil gauge has been fluctuating like crazy. i have a front and back oil leak, but it barely drips. could that be why my pressure is all over the place?
The temp gauge is reading between 150 and 200 while driving. It normally is between 100 and 150. Do I need to have this checked?
How do I test the air suspension rear leveling sensor?
How can I test the leveling sensor on my rear shocks?
