In the last week I noticed a bevy of electrical issues on my 2009 GMC Yukon. Battery replaced about 5 months ago so that should be ruled out.
- Turning ignition results in nothing; repeat and fires right up.
- Door locks not unlocking with remote until 5 plus tries and then just 1 or 2 doors unlock.
- Can remotely lock truck, but alarm won't engage
- Random door locking once put in drive (3 out of the 4 lock); I've replaced all the actuators over time so I don't think that is issue.
- Power running board don't deploy when door is opened.
- Climate control takes itself off "auto" when the truck is started
These are intermittent. When I drove the truck last night, all was good starting right up, A/C as previously set, running board down and back up as designed and doors locked and alarm engaged when I got back home.
ECM?
