My friend is struggling with her 97 4.0L ZJ Laredo. The windows don't go up or down and every time she goes to start it, literally nothing happens. No gauges, doesn't even turn over. I fiddled around with the BCM (09AE) and everything clicked back on and I started it right up, then while running, everything went dead again. I swapped out four different BCM and not a single one worked. I picked up another 09AE from the bone yard and that had no results. For ****s and giggles I tried two different 09AF modules and obviously, nothing. I then lastly tried the 09AE from my 98 ZJ and even still got no results in hers. Both her factory BCM and the 09AE I have started my Jeep, but it then kicked off, probably because of my alarm system, I'm guessing. (Hers has no alarm system)
So, with all this I'm lead to believe it isn't her BCM but maybe a wire shorted or the plug? Anything else it could be?
