Re: [diesel_mercedes] Re: Full heat on all settings except max cold - 84 300D

 

I'm interested in your solution because mine is also blasting hot air - with a one year old monovalve. I'll have to fiddle around too. But, with cold weather it is not a terrible problem right now.

To clarify, the voltage gets sent to monovalve when temp dial is set to max cold, but any other setting and no voltage is ever sent to monovalve.

Could it be:

- cabin temp sensor - $30
- vent temp sensor - $30
- "amp" control unit (silver box) - $125
- pushbutton unit - $175

Don't know which one(s) would cause this problem.
