The 05 SRT Grand Caravan has some window motors/switches etc that have gone bad. My daughter just overheated (playing with it) the one on the pass window so now it won't move. I guess determining if the motor or switch is bad is fairly straight forward- hold test light to one side of switch and flip switch- if light goes on switch is good= bad motor, right? Or do I need to test the relays and all that? Seriously, how often does a relay go bad?

I need to fix the dern rear 12 volt power outlet, one of the rear wing window motors, the drivers side power sliding door lock motor and now the pass side window motor. This is going to be small fortune if I buy all this new. This may warrant a trip to the junk yard. Guess I'll be hauling a battery with me for testing. If anyone has any heads up on trim removal or 'check this first' kind of stuff I'd love to hear from you.

Thanks,
Dan

 

The motor should start working again if it just overheated, otherwise, you are correct, check for power and ground. Same with the wing window motors, that could be either the motor or the switch. The sliding door lock motors are common and replaceable by themselves. The power outlet is spliced in with the front one so if just the rear doesn't work, maybe it's just unplugged.

 

Sweet, thanks. What about relays, testing them etc?

I am finding that some of the 2001 and up caravans etc have the same motors/switches, unfortunately, no nearby junk yards have these models to pick from.

 

Relays are easy to test, there is usually 2 power supplies to a relay. The bottom of a relay is numbered by the terminals, the control side is pins 30, 87 and 87a. Power usually supplied to 30 and the other 2 are the controlled side (whatever you are supplying power to). 85 and 86 are the actuator coil side. Power usually supplied to 86 and whatever controlls the relay grounds 85. So if you dont have power to 2 places with the relay removed, check fuses and such. You should be able to jump power to 87 and make the controlled device work. and you should have ground on the other wire when the relay is supposed to be active.

 

Finally got into this last night. Took it apart, inspected, tested etc and put it back together and it all works. The pass window goes up and down from either switch like normal. Strange, I looked closely at the wires for any sign of damage. My guess is that with the daughter playing with the switch, up/down in rapid succession, it worked a connector loose or something. I'm still a little leary of it but I told my wife to use it but carry a trash bag to cover it just in case.

I have to ask this though. How in the heck do you take off the white clips that hold the motor inplace? It looks like you pull out the head to relieve the tension inside the clip but that didn't seem to work, cuz you know I had to try.

 

You get new clips with a new regulator, so I cut the rear of the pin off from inside the door. I've never been able to get them apart without breaking something. The pin is just suposed to pull out. Good luck with that.

The window motor has an internal breaker in it to keep it from overheating so if the child was constantly moving it, the breaker probably opened. They work fine again when they cool down.

 

Thanks for all of the input. My next venture will be the lock motor on the drivers power sliding door, then I'll tackle the pass side rear wing window motor.
