Hey mechanically savvy Yukon guys.
So here is the run down of the issues I've been having lately along with some back story of my Yukon. Its an 03 Denali not an xl. I've had the 0300 code coming on and off for a while now but usually just wiped it with my cheap tuner. Along with that random cylinder misfire code I've had my service stability message and ABS and traction control lights come on randomly mostly after hitting bumps in the road then they go off. But about a day ago is what brings me to you professionals. My wife drives my Yukon mostly now due to me driving a company vehicle. She called me at work yesterday with the situation of the rear climate control fan refusing to shut off despite turning off the truck and it even proceeds to be on after a battery disconnect and reconnect. After I got home from work I had to jump start the truck due to the fan killing the battery and I removed the fuse from under the hood to stop the fan from draining the battery.
Now today she reports that the truck was idling fine but stalls or almost stalls after shifting to Reverse or to Drive. She can commute this way still as long has she keep the rpms up. After this problem came up she finally divulged to me that it has gone into limp mode a couple random times. This has been our primary and until I started driving a company vehicle the last couple months, our only vehicle. I need to get this beast back into fighting shape please help. Any info or part recommendations are greatly appreciated.
