thanks.- there are two pressure switchs mounted on top of the drier.ones has 3 leads and the other has two.if i unplug the one with the 3 leads, the fan comes on.if i plug it back in the fan shuts off.as of today i no longer have any juice going to the compressor and the a/c light on the interior control panel that indicates the a/c is off stays on. in other words my problem went from bad to worse
