Should we scrap this Torrent?

I had this dropped on me. 2008 Pontiac Torrent, turn signals inoperative,
ABS light on, engine hot A/C off, radio displays locked, and check engine
light is on.
Now for the history.
We had a Torrent setting around for a year because the left turn signal
wouldn't work. Diagnosed as bad BCM. Another Torrent came in with a
blown head gasket. We pulled the BCM out and put it in other torrent. Turn
signals worked but the air bag light was on. We sent it to a shop to get the
BCM flashed. The called and said air bag sdm was bad. We sent that to the
shop. They installed SDM, said vehicle has major wiring issues. We get
vehicle back. We took the motor out and put it in the vehicle with the blown
head gasket. We took the modules out of the car and sent everything back to
the shop that flashed the computers for us. They kept it for 2 months. They
finally said it was ready. We get it back with the issues noted at the
beginning of this post. None of these problems were in this car when the bad
motor was in it. Could the problem be the body module. This car is AWD the
other was FWD.
