2nd Gen Non-Engine/Transmission window switches

I noticed an odd occurance the other day. When I press the window switches forward and hold them there it sends the volt gauge up and the headlights get noticably brighter. Any ideas what the problem might be. Also I seem to have a leak. The weather stripping of the truck needs to be replaced. Is it a hard job to replace and where is the best place to get the weather stripping.

Holding the window switches up forces the motors to stay on, trying to keep pushing up and the glass. This creates a heavy load on the electrical system because of the amp draw. Most power window motors have a "thermal protection device" that is basically a temperature-activated circuit breaker. When you hold the switches on like that, the heavy current heats up this device, and after a little while it kicks out. It's designed to protect the motor from overheating in the case of a stuck switch. When it kicks out, the motors are no longer drawing amps from the electrical system and the voltage goes up. It's not really a problem.



Weather stripping: I dunno. It would help to know which weather stripping you are looking to replace. Lots of different pieces of it around the doors, windows, rear slider, cargo lamp, etc.

I need to replace the weather stripping around the doors and along the bottom edges of the door windows on the outside. Thanks for the reply regarding the swithches, that makes sense.
