2001 e39 540i m sport //AC condenser issue with wires being torn

Hello, appears my AC condenser had suffered some wires being torn when the water pump blew, causing the belts to snap. Although all was replaced but it seems my mechanic had missed this AC condenser with the wires issue. Basically when the AC is on it does not blow cold air. When k bought it back to mechanic they said it is holding freon but due to the wire being torn. They will have to take out the piece and see if they can savage it or replace another AC condenser. Any ideas? I am kind of lost as I felt thy should of seen this when replacing my belts n water pump and such. Seems like double work to me especially when they are a Dinan BMW shop.

Take it back and get them to sort it.

BTW, you do not have an M-sport, unless you have a Canadian model.

Condenser is the AC radiator in the front of the car. If the condenser was damaged the system would not hold refrigerant.

I think you may mean compressor, which is driven by the A/C belt. There is a single trigger wire that controls the compressor. When a water pump goes, it takes out the serpentine belt that drives the alternator and power steering but the A/C is a separate belt. I don't know why that would cause the trigger wire to be damaged though, as it is on the outside of the compressor far away from the rest of the engine.

I think what they are saying is that the compressor is not coming on due to the trigger wire being damaged. The wire unplugs from the compressor, so replacing the compressor would not help if the wire is damaged. The wire is very simple so it could just be repaired without removing the compressor.

I think it's possible that they may not have seen damage to the wire, although it is weird not to have tested the A/C after replacing all the belts.

Hopefully that will help you with your discussion with the mechanic.

I have the thicker black wire covering thinner wires intact and I have an grey or silver thin wire which is torn and looks like it's placed on the ax compressor itself. I guess it's an ground wire of some sort.

OK I see the single wire you spoke of and the wire loose I was referring was a thinner grey one which I believe is the ground wire. However while trying to secure the ground wire I did the opposite and tore it off the Compressor. Will a speaker wire work I'm place of the ground wire?
