Moving this thread to the Winnie Owners Forum...only the on-engine parts are provided by the chassis maker.

The in cab heater controls will be from a third party supplier like Evans/Tempcon.

Go to Oemy's web site - RV chassis parts and you will see a part number for W chassis for your heater control valve. You can purchase it at any parts store.

I may be wrong but the valve on Oemy,s website looks to be the electric controlled one.

pattcook, part number 74612 is a vacuum valve and looks like you can get it at most auto supply stores.

I have finally determined that I have a vacuum leak at the ac-heater- def- vent switch on the dash. For the life of me I can,t figure how that switch comes off. I can,t find any screws or bolts and it appears to be pressed into the dash. Has anyone had to replace this switch and if so how did you get it off? thanks- John

OK I found the two press nuts but they release the vacuum lines from the switch. Trying to figure how the switch comes out from the dash. When I remove the knob I can see 2 small square studs that are pressed thru the dash panel. From the picture of the switch it looks like there is an attatchment bolt hole. Thanks for the part #.

Ok so I changed out the switch. quite a job. I think I dropped that little screw about 20 times. Same thing though the valve stays open. Another question. How does the temp control switch figure into this? I don,t quite understand when the heater control valve opens by vacuum it opens all the way then how does the temp control work? Again I hook a new control valve up to the existing vacuum line and it won,t close either. The vacuum appears good as it opens all the vents, dash to floor, dash air etc.

I had to replace the blue and the green vac lines ---very small cracks hard to see-- replaced with vac line that slid over the existing line I cut it at the fire wall and ran it to each valve ---I think it was 1/8 "ID

The blue and green vacuum lines are the ones in question for me. we verified they were good by jumpering from the manifold vaccum directly to the blue and green tubes with a little piece of sprinkler tubing. The heater control valve opened and closed correctly. this eliminated the control valve and the tubes. When the manifold is connected back up to the switch is where i,m having the loss of vacuum. The new switch seems to be leaking internally like the old one. The manifold is making good contact but when the switch is turned to max ac or off ( the two positions that close the heater control valve) vacuum loss can be heard and felt coming from the switch itself. Hard to imagine the new switch is bad also but I,m at a loss at this point unless it really is the switch.
