1988 560 SL a/c
 Hi,
We have a 1988 Mercedes 560SL. The car wouldn’t start, but this was fixed by replacing the fuel pump relay. However, the a/c compressor then failed to operate. We checked that refrigerant is o.k., the blower works o.k. and we have put in a new a/c relay, but the compressor still fails to switch on. We still wonder if this is related to the fuel pump relay, since the failed nine-pin unit was superseded by a new replacement unit which is now ten-pin. Is there anything else we should have done when replacing the fuel pump relay, or any other part we should check?
Thanks
