The problem still looks like its in the blower case. I have to get a Volvo turbo wagon back on the road before I tear this one apart so it will have to wait for the weekend. The volvo needs a tailshaft bushing and seal replacement. Working on top of the benz will be a welcome relief after crawling under the volvo.
Life is grand when you have a driveway full of old cars, all calling out for your attention!!:p
