big_kev Posted July 19, 2009 Report Posted July 19, 2009 You should clearly hear the engine revs drop when the aircon is switched on the pump places a large load on the engine.If you don't hear it then the pump is not switching on.....for whatever reason. When you say all controls become faulty !......which ones exactly...do you have dual air con.....vents in roof at the back. Quote
sepulchrave Posted July 19, 2009 Report Posted July 19, 2009 I know it's difficult when English is your second language, but if you could try and expand your description of the fault(s) it would help us to help you better. :D Quote

This effectively tests your pump/compressor - and it's free! Quote
