Yukon Electrical Issue by dg6450

2003 Yukon Denali with approx 110,000 miles. The dome lights(frt to cargo area) are engaged and will not switch off. The switch dimmer is working but will not shut lights off completely. Is there a way to isolate the problem to a faulty switch?

steering by roughd1

I have a 04 Denali XL. There is a humming noise and a slight vibration in the steering wheel when making left turns at a stop or slow speeds. Turning to the right is as smooth as ever. The noise is similar to what a vehicle makes when the power steering fluid is low, I have checked and double checked the fluid and it is where the manual says it should be. Had this problem before when the vehicle was still under warranty, the steering gear was replaced and I didn't have any problems again until recently. Had a front and rear wheel alignment, vehicle rides well but still has the problem. I'm worried that it could turn into a major repair if I don't find the problem soon. Any suggestions or ideas out there

The tires are in good condition and recently rotated but I'll have them checked. Thanks.

i notice there is space for a second battery. is it possible to install a deep cell battery for accessory use using an A/B switch without harming the electronics on vehicle or voiding the warranty? i have used this system on boats but dont know if it translates to autos.
 
also, my owners manual was stolen (looks like a purse) dealer wants $85.00 for new one..is it downloadable?? on the web?..
thanks

First answer yes you can get a second battery for that spot. Dealer install is about $500 they may not know what you are talking about tell them its the police package. If you want to do it yourself I have the part numbers:
25825642 Cable
15888242 F Cable
14005061 Retainer
11509853 Screw
 
Second answer, go to gmc.com and get an account. You can download the owners manual from that site.

We had the same air conditioning problem on our 2005 Denali. The dealer stated they had to replace the "actuators" that direct the air to the driver side. Fortunately, these were covered by our extended warranty.

sounds like your voltage regulator is no good.it's inside your alternator.

battery dying ,i have an idea which i will try! by luv_my_honda

the denali uses alot electrical components which is almost as bad as having a sound system.i've decided that i will upgrade my alternator to higher amps not voltage.having higher amps allows more power usage.i'm trying to allow the battery to charge without having too much drain. my 2005 denali dies if i dont turn it on for three days.as im driving i can actually see the voltage drop every so often.alternator is working perfect battery is good but like i said maybe the denali requires more amps.i will post and update.

2005 GMC Yukon Denali bucks when cruising at constant speed... by yukdenali
Aug 28, 2009 (2:13 pm)
Reply
My 2005 Yukon Denali drives well except when cruising at constant speed. The vehicle occasionally bucks/shudders repeatedly until I either press down the pedal to accelerate or let off the gas. This happens at low speed as well as on the highway. Not sure if this is a fuel injection or tranny issue. It does not happen all of the time but enough to cause concern.
 
Any help to troubleshoot this problem would be appreciated.
