I have removed both knee bolsters, glove box,etc. All the actuator motors seem to be working all the flaps. Looking up through the right floor outlet vent,I can see the defroster/floor flap move. The recirc motor & flap works. I pulled out the Blower Motor Reistor and Evap Core looks clean,no blockage seen. With Blower on High & Resistor removed, the air escaping through the square resistor hole is tremendous in velocity! The air just is not getting to the outlets. I am second owner, first owner was also faithful at maintanance, including new cabin filter every 10,000 miles. I DON'T want to remove the dash, but I am at a loss to the blockage. Is there a flap closer to the defroster ducts that I am missing? Is there a good HVAC Diagram somwhere? Any ideas?
