Question about 2007 GMC Yukon Denali
After shutting off vehicle, I can still hear the CD/DVD player trying to run even though there is nothing loaded. Can't stop it. Battery will drain overnight.

SOURCE: CD Player wont take a CD
A lot of the electronics need resetting. Disconnect the radio(easier to just do it at the battery and restore power after a few minutes and let the computer reset) see if it resets the audio system. Otherwise you're looking at a remove/send in for repair and or replace the head unit. Its a nice radio but at the cost I just replaced mine with aftermarket. Depending on system you have(Bose-amplified or non-Bose ) you will need a Metra GMOAS-04 or 01 to retain warning chimes. I can get them cheap...let me know which way you want to go? Good luck!

I have the same problem. I have also been searching the web for a solution. I came across someone saying that it was the heater module located behind the glove department. I can't find now where i read this but it said the part was approx. $150.00. He was having same problem as us, heater wouldn't obey touch commands to turn on/off or when heater did blow it would only blow real low or real high. Like you, after turning off engine blower motor was still running even though it wasn't blowing air out.
I'm tired of paying for things that are not due to normal "wear and tear" on my 2003 Envoy. Let me know if this helps you and how you repaired it. I'll probably have to take mine to the shop but because I'm a "girl" I swear they think I'm crazy with all my Envoy complaints.

The easiest way to find the draw is to take a volt/ohm meter and remove the positive lead and connect the meter in series using the amp meter selection. By series, I mean hook the black meter lead to the battery, and the red meter lead to the battery cable.
Check your amp draw. (make sure you remove the bulb for your under hood light and everything off and closed. It should be milliamps.
If you have a more than several milli amps, start disconnecting fuses on at a time and put them back until you find the circuit that is drawing down the battery. Once you find the circuit, then it gets down to finding out whats shorted or bad in that circuit.

We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.
