86' 420sel climate - heater

I recently bought an 86 420 sel.

The heater does not work, unless the car has been completely turned off and started with the heater on. Then it only blows heat to the front. The back vent blows cold air. If the climate control temp is touched or any of the heater option buttons are touched then the heat stops, (and I get cold air.) The fan setting have no impact on any of the above.

To get the heat going again, I have to turn the car completely off and wait a few minutes befor starting again.

I have searched the forum and not found a problem exactly like mine. The closest I got was to rebuild the monovalve. Would this do it?

Also, if I need to get at the climate contols how do I pop the wood face off?
