New water control valve and AIM cd on the way.

I only get air from the passenger vent located on the lrft side of rhe console. Doesnt matter what position the selector switch is in. I have vacuum at the end of the tube that feeds the water valve which I now plugged waiting for a valve to attach it to! The vacuum does go on and off as I adjust the temp control. This does verify that I have vacuum in the cabin area.

I suspect I might have a bad vacuum controller. So can you help me with these questions:

Does the vacuum controller wear out or break?

Is it rebuildable, or even worth rebuilding as a new one is 15 bucks?

I can't remove any tubes on the back of the controller feeding into a clear plastic fitting . Are these things glued in never to be removed?

What turns on the air conditioner?

Thanks

If the air is coming out at the floor...you are in 'default' mode. I would change the vacuum switch if for sure you know you have vacuum coming in on eh solid black hose in the clear connector.

I installed a new water control valve. It works. I now can control the heat. An added bonus is I now can control the air to the defroster, dash vents or floor! I guess the open vacuum line was my problem. Now onto air conditioner.

Thanks for the help.
