I Have A 2001 SS Just Replaced Battery Alternator &
BCM. When Battery Was First Placed In The Car It
Cranks Right Up No Problems. However If I Cut The AC
On The Batttery Guage Drops And I'm Not Able To Crank
The Car Back Up Unless It's Givin A Jump And My Fans
Aren't Coming On What Should I Do?
Is the AC working fine? sure seems its pulling a HUGE draw from the battery, If you don't turn the Ac ON is the system fine NO battery drain? That's the first check. NEXT, did the fans function correctly before the parts change? Why all the parts changing BCM, Battery, Alternator? any DTC codes before you started...
Ditto on what Auto stated, was the BCM flashed for you Vin before you installed it?
