93 voyager radiator fan and AC clutch

I have a 93 Voyager with 3.3 engine. Within the past couple of weeks
the radiator fan has quit turning on, and the air conditioner quit
working. They both quit at the same time as far as I know. The AC is
still fully charged, and all of the dashboard controls work including
the blower, etc. It's just that the clutch never engages.

I got the trouble codes by turning the key, and it gave me code 33,
which according to the manual is a short or open condition in the AC
compressor clutch relay.

Does this relay control both the AC clutch and the radiator fan? There
is only one fan, rather than one for the radiator and one for the AC.
So it makes sense in a way that a single fault could disable both the
radiator fan and the AC.

Looking at the wiring diagram I also see a "high speed fan switch" and a
"low speed fan switch". The fan never turns on, so I'm thinking that
the problem is not likely one of these, but I could be wrong of course.

Is there a common failure that occurs with these vehicles? Any advice
on where to find the switches and relay for this system? Unfortunately
the fine folks at Chrysler decided not to label any of thes switches or
relays on the vehicle for some reason. I'm sure they're having a good
laugh about it now...

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

 

The ones called out in the factory service manual.

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 ! )

Not so on that year vehicle!!
