Hey folks, I drive a 323I E46 and last weekend I took the car to a stereo shop to install a full stereo system. The guy was trying to find out the rear speakers wires so he made a bridge on the wrong cables and shoot the battery terminal cable detonator



Now I know it is damaged and I have to replace it, the air bag light came on... after that the A/C does not work so can anyone tell me if it is because of the same issue??? Everything looks normal with the A/C lights but there is not air flow anywhere.
Thanks for your inputs... are really
