Need some help with this one, how about it rtg143, up for a challenge? My rangers air flow system is locked onto defrost, the switch still physically works but you cannot chose where yo0u want the air flow to go, it is locked on defrost setting. The hot and cold and fan speed both work fine, just blows through the defroster all the time. Any suggestions that would keep me from having to take the whole dash apart? Many thanks for some help.

Look under the air filter box for the round black sphere.

It has on vacuum line coming from the engine vacuum tree and an output vacuum line goes to the firewall, then to the controls behind the glovebox (pop that door all the way open to inspect in there).

It's common for a vacuum line to break/melt and it will default to Defrost.

Here's a picture of what you are looking for:



In that photo, my fender liner has been removed. The sphere mounts to the passenger side fender liner and is hard to see unless you remove the air filter box.
