Ok, so I may have jumped the gun about charging the air conditioner. Seems I have plenty of cold air in the rear when I turn it on, but up front it blows HOT air. Kind of like last fall when I had heat in the back, but COLD up front. We put in a new "door actuator" up front and were good all winter. Now this! Did we maybe put it in wrong? Backwards?
Have 2001 ford windstar front ac blows hot but rear blows cold any idea what problem is and how to fix it?
It sounds like maybe the blend door is not freely moving, this will destroy the new actuator very quickly, did you check the blend door for freedom of movement when u replaced the last temperature control blend door actuator?
THE TEMP CONTROL IS ELECTRIC, SO VACUUM loose is not the issue here.

No, don't hear any hissing when it's operating. I just had it in the shop for a tune up, and they checked it all???
My son did this part of it, it seemed to be moving freely. I will have him get up in there and check again! Maybe it is stuck again, although there is not knocking noise since we replaced it.
Do not know if they checked the vacuum system when they did the tune up. I know they replaced a filter for the heating/cooling system? (besides the regular air filter!) I can ask at the shop.
Did you ask them specifically to check the vacuum system? That's not included in a routine tune-up.
Sounds like a leaking, broken, or loose vacuum hose. Did you check all these? Do you hear any air hissing when you operate the controls?
