This pretty good testing. It tells you that the GEM is likely not the source of your problem(s).... but it is trying to tell you something. Of course, by not plugging in the shift motor, you eliminate the fuse blowing problem... so that's one issue (if I recall, you indicated that the module was "scared" with "smoke" to indicate a problem... did you check out its circuit by testing between pins as suggested in recent post by others).Thanks for all the help guys, here is the latest..... GEM out = no windows at all. Fuse 26 blows as soon as the shift control module is plugged in. If I leave it unplugged everything works but battery goes down, windows and blower motor work with key off even after doors are opened. Checking relays... If I read the diagram correct the GEM sends a ground signal to the acc and batt saver relay. If this is true they are grounded at all times on mine and should not be???
yes but that was because you had another issue of melted wires going to the relay module. Remember you have multiple "onion skins" here and your "peeling" is just continuing.... just go slow.... you will get to the "soup".I didn't think about the GEM getting the signal to tell eveything to ground I was just thinking that the GEM is JUNK and sending out a ground signal, i.e. causing my problems. Yes I tried a different GEM but found out to not be exactly the same 4x4 system and caused my wipers to come on by themselves LOL. I will check out the "power up" to the GEM and see whats going on. And yes everything blew even with the shift motor unhooked.
