Here is the lowdown. 
1984 Vanagon 4 speed-electric radiator cooling fan is always on-even when totally cold and the keys aren't in the ignition--had to pull the fuse to stop the fan from blowing. I have made sure the A/C is in the off position. the upper passenger A/C control knob feels a little beat--doesn't click when turned to off--just kinda grinds into the off position--I don't know if it is related. 
 Also-I had my neighbor take a look at the A/C--it wasn't blowing cold. Compressor kicked in and things looked good-(found one bad O-ring). So we ended up retrofiting the high & low fittings and put in some freon-the low side pounds were way too high-didnt even take a can--He thinks I need an expansion valve and a dryer couldn't hurt
 Are these two symptoms related or am I looking at two separate evil entities at work here? I can live without the A/C but I am afraid the van cannot live long without me fixing the radiator fan. Any and all  comments appreciated.
