At last got everything else sorted on my 91 940 2.0 turbo. Time to check aircon,Clutch on compresser never kicks in,I believe that connecting both terminals on main ac unit should make it connect but it still does nothing,so is it clutch at fault or is there a relay or anything in this circuit.

Have you checked that there is any gas in the system. There is a low pressure inhibit switch somewhere in the control system which stops the compressor from running if the system has no gas in it (like mine, with a duff condenser at present). This is to stop the compressor from damaging itself as no gas also = no lubricant.

there's a couple of sensors on the front of the aircon radiator as well on my car so i think there high and low pressure sensors as well
