how to fix air flow problem in dash

Mode door actuator.

If blowing out of defrost only..... check for vacuum leak ...under hood most likely on passenger side firewall..... small hose or plastic tubing..

If you can't find the connections. Call Adrian at Contra Costa Auto Service (925)798-1205 and have the guys diagnose it for you. Summer's almost here and warm days are among us.

my wife just had this problem... the fan was running but no air flow came out inside.. I figured out it has to be blocked inside where the fan motor is bolted under hood.. I unbolted the fan motor, very easy to do, and found the entire vent casing was clogged with leaves.. I mean full of leaves.. I dug them out by hand, then also used a vacuum.. wow.. the air inside the van will run you out of there now..BIG TIME DIFFERENCE..Let me know if this helped you..my name is Jay.. from plant city florida..
