heat control in 1985 300D
I cannot control the heat in my 300D. On the defrost mode it blows only hot air, in other modes some minimal control of tempature. Is this a defective climate control unit or something else.

It could be the monovalve which is under the hood on the passenger side of the firewall. To check the valve, unplug it at the top, solder a couple of wires to a 9v battery and touch them to the monovalve. Keep a hand on the monovalve. If you feel it clicking on and off, the valve is probably ok. If you can't feel it, Henry Schuman has the best price I can find for the valve kit.
It's easy to replace. Simply remove the 2 common/slotted screws, take out the top, and pull to remove the valve. Then merely slide the new valve in, replace the top, screw in the 2 slotted screws, and Voila! it's done.
If it's not the valve, go to Schuman's site for more detailed info...
