gotta junk douvalve?


I have been researching problems with my duovalve 1994 c280 because I have cool air from the left vents and warm from the right. I was going to replace the duovalve. I decided to see if it could be repaired. when I took off the caps I found one of the valve (look like a mushroom cap (brass?)with a long skinny plastic rod) was broken in half and the broken piece was laying in the resorvoir. I removed the broken piece (which it would appear is causing the problem. Would it cause the valve not to open and therefore cool air on one side and warm on the other? Does anyone have a bad duovalve they want to part with cheap or even just the little valve?

Thanks for the help.[:D]
