I have read and found nothing specific on how to actually removed the push button climate control until on my 85 300D. My defroster vents blow all the time and I pulled the bottom dash cover on the drivers side and checked the vacuum pod for the defroster and it holds vacuum. The two vacuum lines going to that pod do not have vacuum on them no matter what button I push. I would like the flap to close so I get full air through vents when AC is on.

How do I removed the climate control unit or test it now?

Thanks
