Odd interior light issue

[JTryles]

Ever since I had the dealer replace my ECM (they killed the original when doing the hard start TSB) my interior lights go off VERY quickly after opening a door, even if I use the switch to manually turn them on. Average time from door open to lights off is 20 seconds!!!! It's really annoying! #@$%! Any ideas???

JTryles,



My truck is doing the same thing only without the ECM replacement. Did you get the issue resolved and if so what was the problem? I agree, it's really annoying. Thanks in advance.

you may need to have the dealer go through the dome light configuration as the FCM may think the wrong one is installed... .

Oddly, the day before I was goingto finally break down and take it to the dealer... it fixed itself! Go figure!
