Title: 1994 Winnebago 29RQ Dash AC Problems HELP NEEDED
Post by: whitlow on October 04, 2017, 06:55:24 PM
So I just bought this and have been going through things I tried the AC when I first drove it and the blower was working but no cold air. I thought a shot of Freon would do the job but NO. I started it up turned on the AC to max and tried to add freon but it would not take any. the compressor will not turn on so I tried to jump the low pressure switch but nothing. I started looking and found that the cond fan was froze up and has over heated the wire connector to it.I have no power the the fan and can't find a fuse for it. Can someone out there help with advice as to what to do/look for. I also found a burnt into wire on the battery junction block on the firewall the wire all the way to the right. It has power from the block still .
Thanks

You have a real project there. Have you downloaded your wiring diagrams?

Do your wiring diagrams include the dash air wiring? Is this a Workhorse chassis?

This is the P90 GM chassis I got the only wiring harness diagrams I could find. No luck finding what I need I was hoping somebody out here would be able to help me in some way

I'll move this to the Motorhome board, maybe you'll get some better hits.

you could jumper to the compressor clutch to see if that works... only need power there for a few seconds though until you know more about the problem.  If the condenser fan is frozen, that will need to be fixed for sure.  Might just need to take it to an A/C shop?
