Default MORE Electrical problems!!!!

The rear electric window packed up today it will wind down but not up, ive had the motor out and checked it and it does run both ways so im guessing it may be the signal from the canbus contoller, any thoughts?. Also the blower motor has gone again i checked the connecter on the fan switch but thats ok so i will check the resistor block tomorrow. I really don't need this in the freezing cold so any more advice appreciated

Cheers

There is no can-bus communication between the window motors. It's just a simple circuit. Have you tried putting the window up on both the driver and the rear passenger switch? There a quite a few people on here that have had water or something get into their driver side door switch and corrode the terminals and that causes the rest of the switches to not function. When you said the motor ran both ways, did you mean that it works with the wiring that's there and no load on the motor, or did you take it out and test it with a power supply? As for the blower motor, it'd have to either be a fuse or the resistor. There really is not much too those circuits. Let us know what you find.

Neither of the switches operate the window in the up direction, when i said the motor ran both ways i took it out of the door and tested it directly off of a battery then swapped the wires over and the motor ran the other way. As for being a simple circuit i guess its only simple if you can read a diagram which unfortunately i cant, if it only had 1 or 2 wires to it i could probably work it out but with multiple wires it just messes with my head. I will be testing the resistor block today.
Cheers

anyone got a picture of where the resistor block is cos i cant see it.

Cheers

Sounds like your window switch itself has a bad contact. If your motor moves both ways, then it is likely your switch.
The resistor block you speak of should be right near the blower motor. Locate the pigtail for the blower and you'll find it. Both cheap and easy to fix.

sorted the power window, it just needed a reset from the safety switch so i disconnected the battery, left it for 5 mins connected back up and bobs your uncle all works, so all that work for nothing, well at least i learnt something. Now to the blower motor again, checked the resistor block and all seems fine i have a different resistance between the terminal that connects the 2 together and to each individual terminal, i also tried disconnecting the connecter block from the switch and link with a bit of wire between ground and all the other terminals to see if it was the switch, but that didn't work so i guess it must be the motor, the connecter that goes into the fan is that a ground and live if so i could check the switch and resistor block from there see if im getting 12v and a resisted 12v when i turn the fan switch? feel free to Skype me(neilallen45) if anyone wants to as its easier to talk and understand things.
Cheers

Have a look at the wiring http://www.dodge.com/bodybuilder/200...nditioning.pdf

So 12v comes from the Ing Switch to the blower motor (pin 2). The ground then runs from the Blower (Pin 1) through the Blower Resister and then through the blower switch to ground.

Hooray blower motor fixed, it was a loose wire on the ignition circuit, took me ages to trace it and it was snowing, cheers for all you help
