Climate control wheel broken, stuck on MAX HOT!!!

Searched the archives and found many problems with A/C. Mine is broken and I don't use it, so I didn't care. My problem is that during regular non-ac use the temperature wheel doesn't control the temperature. It's just blows super hot air with of course the exception when the car is warming up. It's winter now, and I have to have the window cracked open to cool the interior. Any known fixes? My car is a 86 190E 2.3-16. Thanks in advance.

It will have to be checked out, but it could be as easy as a vacuum leak in the supply line. Remember, the default for all Mercedes autos is full heat.

1. I do agree with Benzmac the default is full heat.
2. When you say the wheel is broken do you mean it will turn and turn without stopping at full cool or full hot or actually can be pulled out? If this is ok then it should not be broken.
3. If you move the fan speed lever to the lowest setting then push the defrost button does the fan speed goes up? Also If you move the fan speed lever to the highest setting then push the any of the buttons does it change the air flow or just blow out of all vents? If not on both questions then itís in malfunctioning mode it goes into an override function like Benzmac said.
4. Does the fan seem to go on and off intermittently? Itís actually not, it is timed in seconds. There could be five possible things wrong with the unit so five different time sequences.
5. Just count the seconds or use a stop watch, move the fan speed lever to the highest setting so you can hear it, after one clicking noise from the relay the fan will go on for XX seconds pause for four then on another same XX seconds and so on. The number of XX seconds should be the same every time and not intermittently, this number of XX seconds should also tell you what is wrong with your system.

It spins but seemed to put out only hot air, oddly enough now it works providing me the ability to change internal temp, however there seems to enormous delay it waiting for a temp change(minutes, not seconds). .......
