hvac question
Well I replaced the controller in the dash and now I can get all the vent settings to work.
The cable for the blend door is acting weird, if I turn it 3/4 of the way to heat air comes out of the vents, if I go past that you hear the blend door slam shut and nothing comes out of any of the vents. Still no heat, but the top radiator and both heater hoses get hot to where u can touch them. So I'm thinking T-stat?

Sorry about that, can't touch it and it slams shut with the cable, doesn't matter if you do it by hand or with the ****. It gets so far and I then just slams shut, you can hear it.
So when its in working order the blend door shouldn't be closed all the way is what you are saying?
Also should I replace the t-stat anyways since the temp gauge is only getting around 170*ish if I had to guess based on where the gauge is?
Change the thermostat anyways. It's cheap.
The blend door should be able to go from full hot to full cold and stay where you put it, not have it slam. It sounds like a linkage problem. There should not be much play in the system.

There's another issue. The door "diverts" air THROUGH the heater core when the control is in the "hot" position.
You could have something in the plenum blocking the flow - but the door shouldn't slam shut regardless.
