    Windows wont go up/down

    So after extensively searching i still am lost.

    My windows will not go down. My sunroof and heat/blower motor are both working.

    I checked the fuse and its good, i read about the hook up at the starter, but from what ive concluded if thats bad the sunroof/blower wont work either.

    I spent an hour looking for wires/connection that were bad or unplugged under the steering wheel and there is nothing. Also the C104? by the DME is plugged in if that makes any difference.

    Any suggestions on what to check next?

    i could use help too. my passenger window was shorting before my m50 swap but the power mirror worked, so i knew it was bad wiring to the window motor(it worked intermittenly), but after the swap the drivers side window, which has never failed me also isn't working now along with both power mirrors. what did i miss? im thinkin i dont have power to the doors at all now. if the parts are just bad i'm thinking of swaping to cranks or going door panelless to access the windows at will with tool when i need to depending on conditions, i dont really care just want to be able to control them somehow...even if it is a kinda rigged setup. thanks to whoever can help.

      Maybe a wire came off the window lock button? Do you still have light on the switches?

        Why did you post this in the 24v section?





        Has the black window cut button been pressed?

          Are your switches lit up? If they're not, hit the window circuit breaker button next to the rear defrost button (press it hard).

            Try pulling, cleaning and reseating the plug coming from the door. It plugs into the door jam.

                Interesting.

                I still have this problem ( no windows/blower motor/mirrors)

                Checked all wiring/fuses/relays/grounding/possible bad wires/starter unloader. ..Nothing.

                I've been running with jumped relays.

                Somewhere I have a grounding issue which is causing those specific relays to not ground.

                I'm curious to see if anyone else has had this problem, and what their solution's been.
