91 Camry A/C Center Vent Switch

I have a 91 Camry. In this model there is a manual switch that moves air from forward facing A/C vents to an A/C vent that blows up/back. Generally I
have it switched to the front blowers, unless it's really hot and there are people in the back who need air for a few minutes.
This has worked without any problems until a few weeks ago. I switched it to the up/back position and the air changed to the upper blower vent as expected.......now trying to switch it back does nothing. The switch feels and sounds just like it did prior, I can switch it up and down, but it does nothing now.
Any ideas on what I could do? My guess is that I need to tear the dash apart to figure out how that worked, but I'm not even sure where to start there.
thanks --mike

I couldn't believe my eyes when I saw Mbt6 wrote:

Yup, prettyt much...there should be two screws at the bottom of the dash cover and maybe two more below the vents. Then (I'm just going from memory here...) you might have to remove the radio just to make it easier. Then, there are four screws holding the heater controls onto the dash panel.
Now comes the fun part...the controls are operated by aircraft-style cables that move the various controls around. My bet is that one started getting a little tight, so you reefed on it to get it to move and bent the arm. This operation really is a bit of a pain...one of my least favorite repairs. Take a pair of pliers and CAREFULLY bend the arm back in place.
Or, the cable broke or slipped off. If you're lucky it slipped off; just route it back into the arm where it belongs, maybe giving it a little bend with the pliers.
If you're *not* lucky you either broke the cable at, or it slipped off the far end. You'll have to trace it back and find where it went. On older 'yotas it just looped down to the airbox where you could see it. If it slipped off just loop it back on like above. If it's broke, get a new one and good luck...
