I replaced the battery and the alternator and the bcm is going nuts my drivers seat went all the way up and isn’t responding my liscense plate lamp isn’t working, idk if it has anything to do with the power steering but its hard to turn and the parking brake seems to be acting funny
I tried clearing the codes and it fixedeverything but when i drove it around the block the dash lights came back on
It will only start with the key fob in the transmitter pocket
Like i said brand new battery and alternator
I tried pulling the starter fuse and putting it back but that seemed to make it worse because thats when the seat started acting up
Any advice??
