Fixed It!!! Drove to Ohio and DQ. using the AC. Would not switch over to heat. Found the plug on the back of the control head off compleatly! How does that happen with an engine swap??? Still wouln't work. Took the disk apart. The keeper was broke on one side and the other broke removing it. Used a nylok nut and had to ground down the head and file a new slot. Still no work. Took it all aprt and tested several times. I've got a 12v vac. pump, hand got tired. Tested the hose at the head conector with the yellow trace,,,no good. You can see 2 vac motors to the left of the glove box. The top one is the AC. Yep,,,, big leak. It was off completely. And very hard to put back???? How does this happen. Never was in there!!! There looks like there is a third one below the 2 you can see. Another vac hose headed down. The heat and defrost look like double acting with 2 motors each. One for fully closed/open with the other for 1/4 inch open or "bleeed" mode. The reason why I posted this with detail is I tried to trouble shoot this with out reading the manual and just looking at the diagram. Not untill I read the manual did I notice how the whole system work. You gotsa to have a manual!!! A hand vacume pump, gauge, extra hoses,T's of diffrent sizes, caps of multiple sizes. I keep it all in a small cheep tackle box. Get a couple of tee's that accend in size in steps for troublesooting and repairs. must have for other vehicles too. Now,,,on to the washer pump,,,no power at the pump,,,,oh well,,,,PL
