    No power mirrors, windows, interior lights, or blower motor

    Okay so after driving my new engine swap car I have noticed that I dont have power windows, mirrors, interior lights OR a blower motor.

    I deleted the A/C when I swapped, figured that might have messed with blower motor, but after reading it doesnt do anything I believe.

    I have messed with the window regulator switch nothing changed...

    All of these things worked before my swap

    I have checked all the wires on the starter, they all are very tight.

    My ignition lock thing messed up a few months ago.. so I have to start my car with a screwdriver in the ignition switch. However all the solders on it look solid.

    Any ideas, I really want some of these things to work!

    I will also add that the car starts up fine, and that I know the starter is properly grounded

        So on the starter.. I think I have figured out the problem.

        Does the unloader relay wire goto the upper small stud, or the lower one??

        I only have the thick black/red wires going to my starter and then the thinner one (whose color I cant remember)

          Upper you can test by removing wire from starter and ground directly to block. It is wire on top.

              sounds like classic unloader relay issues. try swapping the wire in question to the other stud, or just going straight to ground with it. all should be well in the end. its a simple fix once you find the wire.

                Straight to ground as in.. ground it to the intake manifold?

                  that is what I have done in the past for testing purposes.

                  basically how the unloader works, is that normally the wire is grounded through the starter, providing proper function of the items in question. During cranking, the terminal is powered (to engage the starter) thereby removing the ground and killing the functions. going straight to ground with the unloader wire will not harm anything, but the items will not cut off during cranking and starting as designed.

                  this was used to reduce electrical load during startup to provide more battery capacity to the starting function.

                    I'm pretty sure it's called replaced a broken engine car, not an engine swap car.

                      sounds like a wiring prob at the fuse box...did you go from square plug to round plug?
                      may you rest in peace, or pieces, whichever comes first

                            So after inspecting my car. The black/yellow wire is on the bottom stud of the solenoid

                            The black/green is not hooked up to anything... is this bad? It wasnt hooked up to anything before my engine "replacement"/swap... everything worked fine then. It doesnt even have a spade connector thing on it

                              Just search green/black and see what that wire does in most threads here on r3v.
