No Dashboard Heat

First Post; wasn't sure to put this post in the Class A Motorhome (2002 Georgie Boy Landau) or the Ford Chassis section. Feedback appreciated. I've attached a picture of a Control Valve (Heater Core to the left). I manually push the lever to the right and I have heat (both input & output hoses get warm). Doesn't move easy. Tried to find a similar replacement on-line but none directly match. The Ford Expedition model is close. Thoughts on the repair/replacement? Not sure what size Ford Chassis I have. It's a 34' motorhome. Hopefully the picture comes along with the post.

We have the same coach - only we’re sitting on a Workhorse chassis.

Dash HVAC the same though - we now have that same valve as I replaced the all metal valve that was on there - Murray Climate Control Murray Climate Control Heater Valve | MRY 74628 - bought from OReillys for ~$18.00.

Thanks for the quick response. Looks like it might work, so will be purchasing it. May be a little bit getting back to you as I need to wait for a warmer day to replace it. It's in winter storage (outside). Again, appreciate the quick response.

FWIW - I had to get a speed clip to hold the control wire on mine - the wire kept popping off.

When you remove cable to check if it is the culprit. You can find vids or links of tricks to push lube into cables. Usually hose, hose cut to make rubber bushing ,clamps and air fitting. That one doesn't look to hard ,if its the problem. Don't get crazy on amount of oil as it goes into dash.

And,... if you find out it's the cable and you want to get lubricant into it do NOT use WD-40 as it tends to attract dirt and will shorten the remaining life of you cable.

Bicycle shops, small engine repair shops and others, have the equipment to lube cables, such as the one that controls your heater valve.
