My 05’ 320 A/C is running and thermostat reads 65 but cabin is not cool.  Sea pump recently replaced and strainer cleaned but pump is not running, is there a fuse somewhere? Pump was working this past Sunday.

    You're saying the display reads 65, even though the actual temperature in the cabin is warmer than 65? 

    If the system think's it's 65 in the cabin, the pump won't turn on.   You might need to adjust the temperature calibration.  I've done it before ... check the manual.

    check where you temp sensor is placed also.  i just found mine had dropped low and was sitting in the condensation pan water throwing off the temp.  moved it away from the unit and all is working better.
