93 Grande Caravan, cant' find A/C compressor fuse

Compressor doesn't run. Checked all relays under the hood for the wire
colors shown in Chilton manual and found the ones for the A/C.
I permanently labeled them for next time.

Bypassed the Compressor Clutch Relay contacts and compressor still
doesn't run. Put 12v on the contact going to the clutch and the
clutch pulls in. (doesn't really sound normal and the little bit I
ran it, I didn't feel any cooling affect on the line from the
compressor. Maybe I didn't do it long enough. )

When I jumpered the clutch relay contacts I also checked them for
12volt with a meter and got nothing. Since the Chilton drawing says
that 12volts should be there "at all times", I think the fuse must be
blown. But where is it? It appears from the drawing that it is not
part of the normal fuse block with all the others. According to the
drawing it is not a fusable link, it is a real fuse. Where is it?
What does it look like? Anybody know?

I'll mention this also, because the same fuse feeds the Low Speed Fan
Relay. The radiator fan may not be working either but I am not
familiar with how it should work, so I am not really sure. I do know
this much. I touched the fan blades and they moved very hard. I moved
them back and forth for awhile and it freed up. But I still haven't
seen it run.

So, anybody know where that fuse is?

Well lets see you need a service manual not those FPOS things, though
I have gotten information out of them that I didn't find in the
factory one.

The thing is that if the FREON is to low the clutch won't kick in
unless you feed it like you did so everything electrical may be fine
but the computer won't let it run because the FREON level is to low
you need to have it checked out properly to see if there is even FREON
left in the system, and if its enough to turn the clutch on.

Same van here, same problem. The fusible link you are looking for is in
a gray wire in the harness under the windsield fluid tank.

When you fix the wire, be sure that the fan doesn't take the whole
system down again. The link burned up for a reason, probably a bad fan
because you don't have any other equipment that's messed up. If it is
hard to turn, that's probably it. Mine was the same.
