Dash Problem
Hey Guys I want to remove my dash,im having problems with my air vents,and to get to them on my 1984 I want to remove my dash,how hard is it to take off. Im not getting the air I should so im inclined to think when I go to close or open different vents nothing is happening,it should blow the air out hard, I can barley feel it coming from the front of the dash,can someone help me Thanks

is this the elect a/c option or the manual?
either way, its the vent controls. First you need to be sure there is vac to the interior. The vac line enters the firewall somewhere west of the distributor on the firewall. There will be a vac line thru to the inside somewhere around the top side of the blower/air exchange box in the passengerside foot well. Find that vac line and trace its route. If its elec a/c then it goes to the programmer over the gas pedal. That is what manages and operates ALL the vents and their servos.. or diaphrams. if its manual these are operated by the cable so trace that to be sure its moving the blend door as it should.
Is most of the air blowing out the defrost? if so thats a blend/distribution issue. Hopefully its the programmer or just a cable.
It would take forever to describe how to pull the dash apart and what to look for so I'd suggest that you go buy a FSM set and have ALL the info in front of you as you attempt this. Its far too complicated to try and describe here.
Without the FSM and those directions and drawings, you can still trace the vac, check the cables (if equipped) and make sure the blower is running high speed.
