Mine took a dump on me last year, I took it apart and parts went every which way! I tried putting it back together, the motor ran for a few seconds, who knows what it was doing!! And all last winter I only had "OFF" or "FULL HEAT". So when I got cold I'd turn it on, when I got hot I'd turn it off. Most of the time I was too cold or too hot! I found a couple of them in the wrecking yard and took a chance on them, one was good, and it's been working fine since. Probably set me back about twenty bucks or so.

Peter G...I'd be glad to learn whatever you have to share about the valve.

Bill.......Do you have any idea if Chrysler used that same set-up on any of their cars, or did they just make it for MB?
