I need help. It started with the driver's side power window not working, then the radio light starting going in and out (the radio works, just no lights), the power locks will randomly lock and unlock (even when the truck is not running), and now my turn signals work intermittently (usually not). When it was just the window, I checked the motor and it was fine, I replaced the door switch assembly, still nothing. Now with everything else, I am thinking an electrical issue is causing all of the problems, but I don't want to blindly go in searching and replacing. Any suggestions would be greatly appreciated.

 

check your grounds, battery ground, frame to block, body to frame

 

^Good idea.

Also, how old is your battery? Clean up the connections on it?

 

Find the gremlin hiding in your truck, take him out, then shoot him til he quits twitching. problem solved.

Like the guys said before me, check all your grounds and connections at the battery. Not sure what your location is, but if it rains a lot, or has high humidity on a regular basis, you may be getting moisture buildup on one of the fuse panels causing an intermittent short. so check your fuse panels for moisture, cracked insulation, random evil squirrels, etc.

 

my two cents is check the tilt steering. common problem for our trucks to pinch a wire up there. pull the panels around the column and stick your head up there with a flashlight. or just try tilting the wheel to a new position. my wife likes to pop mine up all the way and one day she will bust something.
