AC question 5KCSTQ

Mon Apr 11 20:44:54 EDT 2005

Well it's getting warm and of course the AC isn't working.

Relay 11 is not switching voltage to the compressor.

12 volts is on one side of the Relay 11 coil. The 12 volts is  is routed thru the AC low pressure switch. The other side of the coil is high impedance. Is this a switched ground? If so what switches it?

My Haynes manual shows the low pressure switch running right to the compressor with no mention of relay 11. 

Can someone confirm in the Bentley how the AC relay (11) is controlled?
