First is to determine if there is a spurious current leak from the 12 v system. measure the current out of it with a good meter and turn everything off if not already. Start pulling fuses until the source is found and trace that circuit for the issue. The 12V charges from the high volt system if its anything like out Toyota Hybrid. And if it were the HV battery, then charging the 12V one so that you could start should expose a HV battery that shows significant drain from sitting. Does it? Did they verify the inverter (Charges the 12V) is working properly? Think of it as an alternator for hybrids.

12 volt is actually a misnomer of sorts... it's actually closer to 13.8 volts i believe. if the voltage regulator is not working right you could very well be frying the battery. replacing it is the cost of the alternator + labour (unless you do it yourself).

DONT START THE CAR///IGNITION ON//PRESS THE GAS PEDAL DOWN 3 TIMES SLOWLY//THEN START THE CAR. THAT RESETS THE COMPUTER AND THE CHARGING SYSTEM WARNING LIGHT.

Really is the battery symbol in the display, is not the "check engine" symbol?
- Possibly the Oxygen sensor needs replacing as the sympton you describe is usually what happens when the O2 sensor malfunctions
- Had the Oxygen (MAP) sensor changed, and it is running great. Even getting better gas mileage.
- The fuel pump harness, tends to melt, even though it is in the fuel,
this is so common, after a new fuel pump.
Other owner comment for a '95 sedan deville 4.9L... "and my car keeps on cuting off.
Also, sometime it shuts off while driving and wont turn on until a few
hours have passed by. I changed the fuel pump and fixed this problem
temporarily.
Clean out your Throttle body and it will quit. Get some good
carb cleaner spray, spray in the t- body and stick your fingers in
there with a good rag and wipe out the carbon that is built up inside
it. Let someone press down the accelerator to open the t-body up while
you are cleaning it. The start the car and spray some in the t-body
while it is running and stop using cheap gas."
I hope help you with this.

I don't know what you mean by temp module but i'am gessing the switch on the dash, but to me it sounds like the resister is bad, i believe its located under the hood on the air box if not than chk. under the dash by the heater motor, i have seen the wires burn that plug into it when they go bad, thats what makes the blower run and also regulates the speeds of the blower motor.
