s14 interior air duct control problem! GRRR...

[midnight_rex]

I'm having a problem with my interior fan control. The fan blows in all 4 settings but when I try to switch from dash vents to the windshield defroster setting it does not switch. Or if i want to set it to blow to the floorboard only it will not switch. Actually it does this in all settings. Right now my fan only blows out of the dashboard vents. When it rains i would really like to use my defroster but I am having this problem grr.

It used to work before with no problems. Is there maybe a fuse or relay that could have failed somewhere? I don't know where to start looking to find what the problem is. Someone once told me there was some sort of relay that usually goes out when this happens. I completely forgot what its called.

If or has anyone had this problem before and fixed it? It was working perfectly fine before. Any info would be appreciated.
