I also bought a brand new 2000 Yukon with the SLT package and not the XL. It sounds like the main computer that drives all of those things are out of wrack. Because if your battery is dead you need to reset all of those sensors etc. In regards to the factory radio all I did was add (2) 700 Watts amps to it and updated my speakers with Pol Audio and it cranks! However, you can add another radio below the original radio but the factory radio everything runs through it so probably not a good idea to switch it out. You need to get yourself a code reader and plug it into the reader and see the codes that is associated with the issues you are having. Once you start knocking out each code one by one you should have a nice vehicle again. I have 116k on mine and did a 3" body lift to fit my 35 x 12.50 x 16.5 wheels!
I also have modified the muffler and have separated 2.5" stainless steel pipes from the cat back going into a x-cross magnaflow muffler to over the axle and that's it. Didn't have enough money to bring the tail pipes out near the bumpers but that's ok. I don't have any issues like yours though?
 
So get a OBD-II code reader and start from there and get a GM code book to explain what the codes mean and get them repaired or replaced.
 
I hope this helps?

I just re-read your issues and looks like you have a a major short from the headlights that shorted out the "Brains/Computer" or the different control modules that controls the seats, locks, wipers, anti level, etc.. My question to you is how does a tail light crumble and fall out unless you were rear ended and never got them fix? Am I right?

#146 of 150 01 Yukon engine will not shut off by sguild

I have a 2001 Yukon. Yesterday when I got to my lunch meeting I turned off my truck, got out, and I realized the engine was still running.
 
I have an aftermarket remote start, but I have been able to isolate with about 95% certainty that this is not the issue...
 
I was able to kill the vehicle by disconnecting a fuse, but when I re-start it the issue is still there...
 
Anybody ever seen this before?
 
Thanks in advance for any advice...

I have a 2001 Yukon that will start cold immediately (-20c without being plugged in) but once its warm is slow to fire up. Did you ever find a solution to your similar problem

Just read about your problem. I know this is somewhat late, but my 2008 Denali has failed to start on numerous occasions. I initially thought it was battery, but day after putting in new battery, same think happened. I put old battery back in and returned new battery. Dealer checked it over. Mechanic there told me that the relay/fuse box on firewall where battery/starter cables are connected may need cleaning and tightening. He did this and all was well for a few weeks then occurred again. Went back and he said that GM had informed him that there were issues with the battery cables. I replaced the positive cable (expensive) and no issues for three months. Just recurred this week, have just replaced negative cable. We'll wait and see. I think the next thing will be the fuse (120 amp)/relay on firewall (don't know official name of it). Hope this helps. What is the status with your issues? Have you resolved?

I sent an email to the GM rep on this forum Saturday and am awaiting a reply. Same boat with power cutting out periodically over the past week. Bought it used and almost got a year out of it without problems (other than door locks which were already failed upon purchase). I don't mind paying for the cables but would rather not be raped for the labor on a known issue. I'll update this week when all's said and done so others know what they're in for.
