2003 GMC Safari Repair Question
Asked on March 5, 2011
Gmc safari 03 running lights stay on
The car is off. The light switch is off. The parking lights (all four) reman lit. I pulled the fuse ( 9) that should kill them but they stay on. Just before I parked it the auto headlight control was turning on and off. When I parked it the" lights are on "alarmed dinged, but the manual switch was in the off position. To get it to turn off I had to turn the dash dash light/dome light roller switch to the lowest setting.

The lighting system has self-diagnostic functions and a scan tool is required to check for trouble codes which would help to identify and locate the source of the problem.
You should get a scan performed first. These are B codes and normal code readers would not be able to get them.
