A/C questions...1991 300 SE
 
Does anyone have a picture or can they tell me where the a/c valves are ? The high side and low side. On the right (drivers) side I see the window on the condenser? I see another valve on the left(passengers) side I've got to get a manual for this thing. It's nothing like my ford.

ok, it may not be like your ford, but it will have a compressor, a condenser, lines in between, and the evaporator.
follow the line from the compressor, to the firewall that will be the suction line (low pressure) the line that leaves the condenser (in front of the radiator) and goes to the firewall will be the liquid line (high pressure) find the fittings on those lines.

the order of operation of an a/c system is compressor to condenser, to expansion device to evaporator to compressor.

His ford is probably an OT system. Regardless they are similar.
