99-00 GMC Yukon Denali - Electrical bugs
I am experiencing the below problems on my Yukon Denali, any information from those who have experienced these types of issues would be appreciated.
- Occasionally the stereo will stop working, no power, when the truck is put in any gear besides park. When this occurs the windows and door locks will sometimes stop working.
- Headlights will sometimes come on when it is getting dark and sometime they have to be turned on manually.
- Sometimes the truck cannot be shifted out of park without turning the steering wheel first.
- The highest setting on the AC/Heater fan turns the system off

the fan setting sounds like a bad blower motor resistor. The other issues could be caused by a bad bcm. The 99-00 yukon denali were one of the first trucks that gm produced with a bcm. it is located in the center console. I have seen tons of odd issues occur due to a bad bcm in those year trucks.
