2006 Chevrolet 3/4 ton express van, door switch problem?
I have a 2006 Chevrolet 2500 3/4 ton express van. Instead of a simple switch in the door frame, lately the mechanism that turns on the dome light and shuts off the radio when you open the door is failing intermittently. That is sometimes the light comes on and the radio goes off as soon as the door is opened, and at other times it takes a few seconds for the dome light to come on. Then at other times it just won't come on at all.
The matter of whether the light comes on or not in itself is not the issue. I can always turn it on manually if I need to. And I can always manually turn the radio off. My alarm system however needs to see a voltage change at the dome light in order to activate. The dealer says this switch is part of the door latch and can't be replaced, but judging by the exploded view of the door that the dealer sent me it the harness appears to be plugged into the window crank unit. From what I've read this front door/light issue seems to be a common problem and it also always appears to be the drivers door that is affected. Why is that? Can someone please explain to me whats going on with this? Is it repairable? The dealer says you can't just buy the "switch". The entire window crank assembly and new latch is apparently part of this horror show for 600.00 as well. Of course I'm not prepared to go that route. Can you just replace or service a switch that is failing? I don't mind taking something apart to attempt this if it's feasible. Amazing that over the years they went from such a simple arrangement, (a door and a switch in the jamb) to provide a ground, to a nightmare like this. I did notice however that the side door seems to have a conventional mechanical switch that turns on the dome light. I haven't investigated this fully yet. I'm guessing that this arrangement does not involve a module but hopefully either just grounds the dome light or puts 12 Volts to one side of it. In any event I think that if need be I can rig up an auxiliary switch at the front door and tap into the side door wire to do this. It may not turn off the radio when the door is opened but I'm going to replace that with a different radio anyway. As long as I can get the dome light to work when I open the drivers door my alarm system will work. The other possibility is that my old van, a 2002 Chevrolet one ton will be going to the junk yard pretty soon. The dealer says that there is a different part number for that door arrangement but he added that it looks like it could be the same part. Can anyone either confirm or deny this? I never had any trouble with the lights on that van, so if that arrangement would work in my 2006 I suppose that I could try to swap it. I appreciate any advice or further insight on this problem. Thanks, Lenny |
