Thanks for all the advice peeps,
I think by the sound of it I'm not really gaining anything by removing it.
May look instead into repairing it then if it's going to stay.
What put me off originally when it packed up was I'd been told its usually bloody expensive to repair.
When it packed up, all that happened was that when engine was running, if you turned air con on it would stall the engine. So I presume that would mean the compressor is seized & would need replacing?
Or is it something that could be taken apart & repaired DIY style?
