I was at the junkyard the other day and could not find a heater/AC control panel. What I did find is a ton of different Adam panels that look like they may work. So many 6 vacuum ports in the back for controls and a couple more ports off the temp area. Has anyone ever tried to fit the newer 80's control panel into out coaches? They are plentiful and cheap, figured I would ask before my attempt.

Here is an example of what the assorted vacuum ports do at the various settings for the second generation A/C configuration: http://www.gmcmhphotos.com/photos/color-hvac-troubleshooting-charts/p22988-hvac-connection-charts-color-comp.html

Some of the newer (90s) stuff uses different connectors and electrical controls for temp blend and air door control as opposed to bowden cable and vacuum doors. Sounds difficult to me. I would think you could find 80s G, B,and E cars to pull from. I believe our rubber matrix disc is different as there is no BiLevel on the MH.

This coach was manufactured in 8/75 but the TZE decodes as a 1976. Since
the water heater is a rectangular box, not round like a 76 I'm thinking it
may take 1975 A/C controls, and not 1976 A/C controls.

Others will chime in with better info.

Cheers,
