93 voyager radiator fan and AC clutch

Start with checking the fusible links just under the washer bottle on the left fender for a blown circuit.

Yep. There is a relay for the radiator fan and a relay for the A/C compressor clutch. They are interlinked such that the compressor relay won't close unless the rad fan relay is closed. A single fusible link feeds them both. You've got some diagnosis to do -- and you'll need a factory service manual (not Haynes, not Chilton) to do it.

I also have a 93 Caravan with 3.0. It's a different engine, but the chassis wiring is the same as far as I know, and everything on it works. I can do the classic "switch parts until it works" routine with the other van. If I knew which relays and switches to look at, I could determine whether the fault is in the parts or in the fusible links. The problem is that it's hard to tell which ones are which. Does anybody here know off the top of their head which relays to look at?

Check the fusible links as I stated earlier, thats you you want to start.

Yeah, good idea. I've had trouble with those on another vehicle before. And it makes sense if one of them feeds both systems.

Thanks

Sorry...zero tolerance for people too goddamned cheap and lazy to buy the number-one necessary tool for DIY car repairs.

I thought that's what Usenet was for.

I don't know about being lazy, but you're right about the cheap part.

My 95 3.0 they relays are all labeled on the under-side of the power control centers cover. With the exception of two if I remember correctly, they (relays) are also all the same so swapping is what I did to track down that it was a bad Rad Fan relay when mine failed.

Hmmm, I have the manuals for my vehicles, but still have a question or two from time to time. I also find it quite easy to share what I know with others seeking assistance. Not everyone has need for a manual if they do not do ALL of their own maintenance and coming to Usenet groups or other forums is often (as in this case) a logical move. Sometimes they will stumble upon courteous and knowledgeable folks willing to help out.

I guess you thought wrong.

Then I'll add "willfully stupid" to the list as it applies to you.

I'm just glad I could do my small part to help you feel superior today. Let me know if there's anything else I can help with.

wealth of knowledge!! LMAO. when are you going to use that wealth of knowledge of yours on the newer model cars? there arent to many shadows and acclaims out there any more

Also, one other caution about fusible links, check the connectors too. I once had a fusible link on my Datsun go, and the link looked perfectly fine (wasn't all bubbly or burned insulation) the problem was that corrosion had got down and ruined the crimp connection from the wire that made up the link, to the plastic end connector on the link.

Interesting, I have a similar problem with my 1996 Sebring convertible. The difference is this: After a few minutes of running, my radiator fan turns on, even when temerature conditions do not call for it, and when it does, the A/C compressor cuts out. The fan continues to run but the clutch will not engage. If I shut the car off and then turn it back on after a few minutes, it occurs again. I also got a code 33 when I did the key dance.

Now, I have ordered a FSM set. But it has not arrived yet. Where is the fan relay for this car? It's not in the relay box under the hood, though all the rest seem to be.

If you don?t have any luck finding the fan relay in the PDC (under bonnet fuse box) then your vehicle will have a solid state relay system......it?s found on the nearside front chassis leg ( easy to find once you know it?s there but a pig when you don?t ! )
