Check the vacuum lines on the back side of the controller and under the hood

is it blowing at all. is it coming out the defrost only? if so do what bones said and check under the hood to make sure the vacuum line is hooked up. get all air out of system

Ive had the same problem,did you get the gasket between the air box back in place,if not the air will just blow around the core and not threw it.

what if it only comes out the defroster mine wont change to vent or floor but i get plenty of heat just out of the defroster i wonder if the switch is bad

vacuum line under the hood on the passenger side right were the ac pokes thru is busted or disconnected ry that first if not it look at lines behind glove box

[TandTBlackSnake]

Vacuum hooked up.Gasket around box tighter than ever before.Previous owner had broke apart to try and get to core.Air switches from vent to defrost etc.

How about the blend door cable... is it moving the blend door from hot to cold??

As for Wilsmoku, sounds like the vacuum has a leak or isn't hooked up to the A/C switch/control head.

Vaccum lines are screwed. check them that's your problem.

Not to jack the thread but i have a unique situation on my coupe i replaced the h/c and have heat but the vac line comming thru the fire wall is just hooked up to the vac port on the base of the carb /maby not enough vac to work the doors in the heater im thinking i may need the vac ball back under the fender hooked up

go to a junkyard and grab yourself a vacuum tree from a f/i car and the line assembly over the dryer assembly and rock out
