'97 GMC Sierra Interior light issues...
 

Hey there,
Today I experienced something rather odd...
I went to use my indicators and the door courtesy lights flashed on....
Respectively Left and then right, dependant on which way I was turning..
Then they came on by themselves whilst driving straight down the road.....
When I went to lock the car with the central lock key fob, they didn't go out....
I eventually pulled fuse #3 to prevent the battery going flat.
Have any of you experienced this issue and what remedial work was required to fix this?
I look forward to some positive feedback.
Cheers,
Cruisin'
