No defrost in my 300DT
Now that it is starting to look like Winter here in MN, I needed to get heat onto the windshield. I found out that my defrost does not work. When I push the button nothing happens. I also discover that there I cannot get heat to the floor. The A/C in this car has not worked since I have owned it.
Vacuum or CCU? What should I be checking? Sorry, It is a 1985 300DT |

Most likely the CCU, try a search as there have been numerous threads on removal and repair

A word of caution: Before replacing your CCU, make sure you aux water pump is not shorted. This *may* be the reason yours is dead, and could kill your new/repaired one.

The fans are working
The fan is working in all settings but the defrost setting. When I push the defrost button the system acts like it is turned off.

Sounds like a bad CCU solder joint.
