have a 99 also - same problem. Intermittently the radio, wipers, and windows cut out. Get this - if i slam the center console lid most of the time all systems cone back to life.    Spoke to several dealers and no common fuse, relay, circuit breaker exisits and no connection in the console area is common - according to them.    Everything is stock. Have you had any luck.
#486 of 779 Headlamp Problems by 3babies Oct 02, 2006 (4:29 pm)
I have a 2001 Denali and my lowbeams do not work. My highbeams work, my fog lamps work and my parking lights work, but I have no lowbeams. I've checked all of my fuses and they seem to be fine. Also tried to replace bulbs but to no avail. Used a meter to make sure there was voltage coming from the connection. It's all good. Also the lights on my steering column (volume controls for radio) are out. And my 3rd brake light. Has anyone else had this problem?

Replying to: 2002gmcdenali (Jun 23, 2005 11:18 am) It is possible That you had a carbon deposit in your intake plenum, it is the part between the throttle body and the block/heads. If it where blocking a passage it would have created the problem you are describing. Not sure on the warranty end of that. Your lucky it wasn't the EGR valve that clogged and they wanted to charge you for. A buddy of mine worked at a dealership and he would replace the whole part even though all you have to do is take it out and knock the carbon out of the valve seat.

Replying to: keisha40 (Aug 15, 2006 7:07 am) Not sure of that particular motor but most newer cars with a tach run off a cam sensor to measure the motors RPM. It is a little device that runs off a magnetic pick up. That is most likely the prob.

I'm wondering if anyone has had problems with the two rear doors and hatch not locking. I have tried both manually locking from front doors as well as pushing the remote. The two front doors lock but when I go to open the two back doors and hatch, they do not lock and the alarm system goes off. Any ideas or suggestions?

Replying to: boogga (May 12, 2004 5:25 pm) Boogga, did your dealer ever get this issue fixed? Some people say the TXV replacement (Document ID #594045) does it and others say it's a normal whistle noise related to the unused IAC passage in the throttle body (Document ID #1580607).   My 2004 Yukon Denali makes the exact same noise and it drives me crazy!   Thanks!!

Replying to: cdog51 (Aug 06, 2006 5:26 pm) It does work. I wish I had done it before having the fuel pressure regulator replaced in a failed attempt to solve the problem. It has been good for about a year so far.
#492 of 779 2007 Denali Gear Noise by david4266 Oct 23, 2006 (7:51 pm)
I used to be the happy owner of a 2005 Yukon XL that rode good, was quiet and a pleasure to drive. I traded it for a 2007 Denali and what a disappointment. At 38 mph plus there is gear noise. If you let off the gas or take it out of gear it stops. I only have 700 miles on it and the noise has been there after about 100 miles. It is loud enough to hear inside the cabin. The dealer says this is a normal noise in the AWD Denali. I drove several other Denali's and they all had the noise, mine was louder. Has anyone experienced this and if so did you get it fixed. This issue is driving me nuts. Replies to this message: awf_axis (Oct 28, 2006 7:27 am)
