1993 Mercury Sable. Engine running great, Daughter says AC stopped being cold. I turned on AC, and can tell the compressor does not kick in. disconnected and jumpered the dryer wire, (friends advice) still no compressor. Checked Voltage at Dryer, no voltage. Checked AC fuse (15 Amp) and found it blown. (reason for no power at dryer???) Replaced fuse and fuse blows as soon as you turn on the ignition (with ac and heat control off and dryer unplugged). With fuse blown, Heater/AC control changes air direction according to what is selected (max, panel, floor, defrost) But the air comming out of the vents or defroster does not change temperature even when engine is up to normal temperature. Radiator fan comes on when needed to not overheat engine. This is the LS model (fully loaded) where you change the ac and heat by selcting the numerical number on the controller, i.e 73 degrees and the heat/air act accordingly. checked the low side ac line (quick tap on the shrader valve) and there seems like there is plenty of R12 pressure in the system. I was planning on changing it over to R134a but now I don't know. My next step is to try and electrically disconnect the compressor and see if the fuse blows, but I can't find someone with small enough hands to get between the PS pump and the compressor. Any help on that would also be appreciated! Any ideas on why the AC fuse blows??? Could it be that climate control door? Thanks

Any body replace the starter on 91 Silhouette lately? Seems there are a lot more wires passing by, like in the way then pictured in Chilton's book.
