I flew to Kansas City to buy my 300TD in April. It was raining like crazy all the way home, then rain turned to sleet the farther North I got. I was a little distressed to find I had no hot air for the defroster, not to mention the fact that I was a little chilly!

Somehow I managed. One of the first jobs on my new car was indeed the heater monovalve, which was torn like yours, and then the ambient air sensor foam tube. Now works great.
