So we have a 96' Georgie Boy Cruise Master, runs great etc... I have an issue with the front air control that I am hoping someone here has seen before. There are two issues but I have a feeling they are both related.
Problem #1, the lever to change from Hot to Cold, moves just fine, my problem was only hot air was coming out no cold, I have sense then recharged the AC and that's when I realized the problem has to with the valve which opens and close the water line to the heater core, it was open and never closing, I noticed that when I slide it to hot or cold the cable which hooks up to this valve is never moving, now if I manually move it then I get my cold air no problem, just doesn't do it with the controller on the dash.
Problem #2, now this has 4 air control setting, Front, Front / Feet, Feet, and then defrost. The first 3 work fine, I hit the buttons and it will change from upper, to lower, lower and upper, but when I hit defrost nothing changes, it just stays on what ever the prior setting was.
I am guessing this is a electrical issue with both and not a vacuum issue. Ideas on where to start looking for this?
Here is the control for it.
