Have you tried testing the fan relay?
I had one that stuck closed and it keeps the fan on.
Replaced the relay, fan stays off till the relay reaches the temp required
then fan goes on.

Subject: a completely different cooling question

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.
