Climate Control Gremlins
I am encountering the identical problem with my 1995 E320. Yesterday I was stopped at a traffic light in 96 degree Houston, Texas weather and the blower stops. When I arrived at my destination, I pulled the fuse and, while it appeared to be good, I replaced it just to be safe. When I restarted the car the blower ran fine. I shut down the engine and went in.
However, when I later started for home the blower would not work. Just before I arrived at home, I tried it for the fourth time and IT WORKED. Twice today I started the car and the blower worked fine. I have seen this same problem posted on other MB boards , but never a reply.
If you get the answer, please let me know.
