OK guys I posted up a little while back about a wiring problem and I still need some help if possible. I have A 02 vette coupe and about every other week my passenger window will not go up or down. Now when this happens my guages go nuts they all drop to zero and it say on the display to reduce engine power . I have cleaned the grounds behind the headlights and looked around for some broken wires but nothing. When it acts up , if I open the passenger door all the way and then close it it seems to stop for a while. But sometimes I have to do that two or three times to get it to clear up.
Well any help would be soo nice and grateful. Thanks

 

Check the wires that are inside the rubber boot that is between the door and the front door frame. Check for pinched or broken wires.
