    Windows won't go up after 24v and 5spd swap

    Got done doing my S50 / 5spd swap yesterday and my windows won't go up?

    Checked the fuse and made sure I didn't un-wire anything while I was installing the pedal set.

    I'm sure I'm missing somethings stupid.

    It just seems like swapping a motor and engine should have no effect on my window function???

    Ideas??

      I believe it is the unloader relay that needs to be jumped. Honestly I forget but I am pretty sure that is it, do a search

        Sharky has it, your heater fan is off, too.

        On your starter there is a green/black wire. It has its very own terminal on the starter. That terminal provides +12V while cranking, but ground otherwise.

        If you want to thrown caution to the wind and chance the possibility of a typhoon hitting Oklahoma, you can simply ground that green/black...but don't touch that window switch when cranking the motor or we shall all surely perish.

            You must be right as the blower motor is off as well... Didn't notice till you said something.

            Is the relay replaceable or do I have to buy a new starter?

            Ha, I'll be there around 1. If I can get the coolant issue worked out. Still trying to think throw how to bleed the coolant system.

              its more likely its your wiring to the relay rather then the relay itself.

                Did you not read the instructions I offered? It is a 2 minute fix.

                  I did. Thought you were saying that I could fix it that way but it was more of quick fix rather than the right way.

                    Definitely test the scenario by using a jumper on the relay terminals first.

                    Starters can be bad, i went through this experience with 2 Autozone 'rebuilt' starters.

                    The starter was not grounding itself internally, so i grounded it externally by running a jumper wire from the terminal where the green black goes, to the terminal with the braided wire.

                      You should see 2 terminals on your starter. Test them, you will see 1 switch from +12V to ground, that is the one that gets the unloader wire.

                        Ok, so ground the terminal post on the starter not just the black/green wire.

                        Had a test today and didn't get to looking into the Unloader issue yet.

                          Close, you got the symptom...but not the problem. Grey with black stripe in x20 not connected, grounded out and WTF everything works. IIRC it was pin 5 for the unloader relay ground. I told him explicitly to hook up all 4 wires on the starter and he did. It had us boggled for a minute too though, I grounded the pin like you said and noda, jumped K5 and blower is going, traced circiut back from relay terms and waddyaknow. unloader circuilt not grounded mutha fuckkkk. :dot:

                            Samething happened to me with my m52 swap.its pin 15 on your old plug just add some wire to it and ground it on something and that should do it.

                              Last couple posts did the trick for my swap. I just have a bad power connection to the passenger side door window which I'll soon rework. It was bad before the swap so sine I've regained my pre swap problem I know where to go. Thanks for all the help.
