I hooked up a set of gages and the system read high on pressure. We let out some of the pressure and then added freon to the point were the gage read full. Felt the line and it was cold as was the dryer. The compressor nor the aux fans engaged. I did unplug the pressure switch and the fans ran, plugged it in and the fans stopped. no cold air is coming out of the vents. I have purchased new pressure switch, dryer, temp switch and evap switch. and o-rings.

Thanks Sorry for the vague description but I moved this post from Benzworld, and it lost some meat in the transfer.
