Hey! Thanx for the input christo829. In the case of the window, you're totally correct. I am referring to the BCM. My bad on the terminology. And I did swap out the rear switches. No change. The BCM leads to the problem rear window's switch measures present voltage in mV. But should be reflecting around 12 volts. As for the front switches, they are not interchangeable. I would need access to another driver side switch. Which I don't have at the moment. But all other functions are fine. Just that damned window. Oh, and I tested the motor, both, by applying voltage directly to the motor, as well as to the switch. Both work fine. (I previously asked for help with this issue here:

As to the starting/stalling issue, she doesnt stall when the brakes are depressed. She stalls as you are driving, once the ABS/Brake lights come on simultaneously. And when it does, you don't even notice until one of the notification lights (the battery light for example) comes on, or you try to accelerate and realize that she cut off, or that the power steering is out. There's no traditional vehicle shutter before it happens. Also, she only takes a while to start back from that immediate condition. If she's parked, she ALWAYS starts, with the exception of that one time I referred to, when it got hit in the blizzard last month. And as far as disconnecting the Viper, the best I can do is maybe pull the fuse from the brain and bypass module. Disconnecting all those wires is simply out of the question. That would have to be a last resort because I would have to take it to be reinstalled.
I recently checked the fuel pressure when I changed the fuel filter. It was perfect. As for monitoring it during a drive, how would I go about doing that? Please let me know. Thanx again for your input.
