dreaded digital climate control malfuctions

[fiddlersridge]

Hey, I have a 99 gt 4 door with the dual digital climate control. Everything works EXCEPT: I cannot get the a/c to blow on the out the vents in the dash. It blows to defrost and down at the feet great. Fan speed is great and temperature change is great. It will change from defrost to feet great too. There are times when I hit a bump in the road and then it blows out the vent until I stop and turn car off. Any ideas or solutions would be greatly appreciated.

follow that thread to pen up your dash, then work the controls and watch the round vac pump things. they are what controls air flow.

the linkage does break all on its own, so look for that too.
