switchover valve 3 getting less than 11 volts?
1985 300sd (126 body); climate control unit problem...
switchover valve #3 only getting 8.79 volts in heating mode. Gets 11+ in cooling mode. I've swaped CCU's (refurbished) with no change. I've swaped Elec Temp Control box (an old one I had) with no change. Installed new Aux. Water pump. Monovalve works fine. Where else should I look? Wife's car, can't put it back together till it's fixed (or I'm dead!)
