Title: What make is this heater control?
Post by: Rickf1985 on December 11, 2014, 08:55 PM
I tried searching but I cannot find the thread that had this information in it. I need to know if this is Dodge, Chevy, Ford and what year so I can get a new one. It is in my 89 31 foot Chieftain. Thanks.

Rick

I attached a picture, Where did it go? OK, Let me try that again, I am at work, it may be a bit.

I know that this isn't a sure-fire way of telling, but it looks like an HVAC control that Chrysler used in the '80s.  That may help to narrow it down a bit.  Rick

looks like a PO switch out.. not original... know that the rheostats (sp?) are $$ for the fan switch anyway.  I'd say pull it and see if there is a mod # etc on it somewhere.

Yours is identical to mine which is original. Same engine, chassis, couple of years difference, so I'd suspect it is  GM product.
Gather you are having a problem with yours?

Jan 2017 Edit: This one is from a 81-93 Dodge Ramcharger
(https://www.classicwinnebagos.com/forum/index.php?action=dlattach;topic=7541.0;attach=2121;image)

Heater system was installed by Winnebago (not GM).  They, and many other RV Mfg's, used a Dodge based design into the late 90's.

Thanks, Dave.
I assumed that as the controls are somewhat directly tied into the Water Pump and AC Pump that they would be a part of the chassis/engine package bought by Winnebago.
However, given ducting/venting/tie-in with rear heat, not to mention dash configuration and bezels, makes sense that it would be a Winnebago supplied, configured and installed item.
Thanks for the clarification.

Well, I am going to do a little more looking but I have to say that the above link for the Cummins pick up is spot on right down to the plug and lines. I am going to lean towards Dodge on this one. Actually I am going to walk out a little later and look at my 84 Chevy pick up and see what it looks like. It does not have A/C but it should look either the same or completely different. I agree that because it is on a Chevy chassi that it should use Chevy parts but remember, Winnebago was based on Dodge chassis for many years before this. I think they only went to the Chevy P30 because Dodge did not have a chassis that fit the bill for something that big.

OK, Went out and checked plus did some online checking and Chevrolet all used the blower switch on the left. Mine is on the right. Guess that eliminates Chevy.

As far as what is wrong with it, the blower switch is iffy, you put any pressure on it and it will stop working plus as you can see in the pics, the tabs for holding it down are broken on the right. I can most likely fix this one but I do not feel like having to take it apart on the road to get it working nor do I want to chance it catching on fire due to an internal loose wire. I have been in this business far too long and electrical was my specialty so I have seen it all. These are still available so I would just as soon put a new one in and then look at the old one and maybe repair it.

you also may find a part number on it which you can google.

The heater control looks exactly like the ones my father had in his Pontiacs.  Could it be something other than Chevy or Dodge specific?  Maybe simply GM?  Or, is it possible they weren't automotive brand made specfically, but made by a mfg and purchased by GM for installation in their vehicles?

To add to the confusion, the electronic instrument panel (option) on the 87 chieftain RU33 was from Chrysler.

I think that has a lot of merit, most of the electronics out there are from Delphi, in all brands. These switches are not going to be made in house and I guess it is possible that they may use the same switch in a couple of brands of cars. Not likely, but possible. I thought it was the same as Chevy until I looked closer and realized that the only difference was the blower switch is on the opposite side.

I ran one of the visible part numbers on that control for the dodge with the cummins and it is a mopar number.

The part number I can see is for the switch assembly. There are a bunch on ebay in both black and chrome. Here is one:

O'Reillys has the switch, just look up 90 dodge van blower switch. Less than 10 bucks.
Title: Re: What make is this heater control?
Post by: Rickf1985 on December 15, 2014, 11:38 AM
Brian, That is not the right switch, no blower switch on it. Bluebird, is that just the blower switch or the whole assembly? The wires and vacuum lines are so tight I cannot get it out of there without pulling the dogbox and reaching up through there so it is going to be tough to get it out and I want the right parts on hand right then and there. Considering it is 25 years old I figured it is best to replace the whole thing, especially if it is the same as a 90's Dodge truck. If the one with the rotary switch has the same mounting holes I will use that since it is newer still and should fit in there.

The blower switch is separate and is less than 10 bucks. Looks like a couple small screws hold it in. You may not have to take it all the way out to change it.

Might not be a bad idea to invest in a few relays when you replace that fan control... rarely have I seen them not burned from the high amperage they carry.  Redirecting through relays would be wise.
Title: Re: What make is this heater control?
Post by: Rickf1985 on December 16, 2014, 06:19 PM
The relays are a good idea, I wish I could find good American made or German made Bosch relays WITH sockets. No Chinese crap!  Any ideas?

Even crappy relays will handle high current better than the switch alone.  Especially with the rat's nest of wiring in our dashes.  If the original switch burned up (which you haven't said, but I suspect is the case), how close was it to igniting something else?  Buy whatever and carry a spare relay.  How much cold weather use will you drive your rig in?  Would think basic stuff from Autozone would be fine.

If it was a daily driver for rain, sleet, snow or sun, then I might go best-quality relays.  My two cents.
Title: Re: What make is this heater control?
Post by: Rickf1985 on December 17, 2014, 07:45 PM
The switch is acting like a loose wire or connection within the switch. The problem is that the wiring and hoses are so tight it is a major pain to get it out so I want a good one to put in and that way I can diagnose the old one at my leisure. This is not a daily driver but when I need the heat and/or especially the defrost I want it to work.
Title: Re: What make is this heater control?
Post by: sasktrini on December 18, 2014, 01:59 PM
I'm I'm correct, that style of blower switch has a couple spring-loaded contact plates (like on old AFX slot cars) that arc really bad over time.  As the springs get soft and the contacts get dirty, it gets worse and worse.  I have disassembled and polished these contacts with a pencil eraser, but too often found the wiring connection at the switch (or the switch itself) burned and requiring replacement.

Typically, either the hot lead (which the switch diverts to Lo-Mid-Hi) or the Hi circuit lead are burned.  So you may be able to get away with just one relay for the hi circuit, if lack of space or minimal wiring fiddling requirements are considerations.

I have replaced Many burned up blower switches in Dodge vans since they are always on high. They just about always burn the plug up and this one is fine from what I can feel. I will get further into it over the holiday when I have time to work on it.

Rick,


Did you check with Lichtsinn Motors?

They should be able to get that info.
Title: Re: What make is this heater control?
Post by: Rickf1985 on December 19, 2014, 03:36 PM
Lichtsinn would most likely only be able to get me the Winnebago part number and I would bet it is about quadruple the price of a automotive supplier.

Brian, I appreciate all the searching you are doing for me. It saves me time that I really don't have. The image looks right on the one for the 88 Dodge, but it is just an image. I will try to get it out tomorrow and get a better look at it and also see if I can find the problem. I also have a couple other major things going on here so bear with me. Got too late of a start on my wood this year so I am in split and stack panic mode and try to get it dry as fast as possible. A lot of it is dead fall so it is just wet from rain and will dry out in a couple weeks if it will ever stop raining and I can uncover it.
