Looks like I'll have to tear into some more this weekend.
Where'* the door located that switches it from floor to dash to defrost?
first check to see if you have vacuum to the HVAC unit inside the car. No vacuum means now vacuum motors pulling on doors and the default position is for defrost for safety reasons.
Ifyou take off the hush panel above the passenger'* feet you'll see a violet vacuum tube going up toward the firewall at the right side of the car. There'll be a connector to the black tube coming from outside. It pulls apart there and you can check for vacuum (with the motor running!).
You can check for vacuum under the hood by following the vacuum tube from the top of the motor to the Y connector next to the accumulator for the AC and then the line goes to the storage container for vacuum. That might be cracked and letting air in. Check the line for cracks.
Do the last paragraph first. It'* easier.
