come on and my car is stuck in 2nd gear my
blinkers will not work and my windshield
wipers are not working can somebody tell
me what's wrong ?
Did you use a preset saver tool[see pic] before you disconnected the battery to replace the alternator? If the answer is no, then you have lost all of the factory presets in the BCM, if it does run take it to the dealer and they can re-flash it to match the Vin, then you systems will come back online.
