Hi guys

I think my Air-Con Pump is broken,
The air-con doesn't cool, there is a burnt clutch smell coming from somewhere close to the pump & now a rumbling noise that comes and goes.

I've used a long screwdriver to my ear against the pump and i'm sure the noise is coming from it.

There is a back disc the same size as the air-con pump pully on the front of the pump , should this be going round??

I take it the only course of action is to change the pump??

Thanks Gareth
