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... |

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. |

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? |

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 maxpower wrote: > Check the fusible links as I stated earlier, thats you you want to start. |

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.

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. |
