Guns- thanks a million. I talked to Rusty there, he sent me the part (BEHR, just like the one I took out) for the 320 Mercedes. $154 as advertised, to the door. I did find the need to reuse the red wire from tho old regulator, as the one on the new part was kinda short. Also, I found it easier to remove the blower motor complete, replace the regulator (2 screws) and replace the entire unit. It was much easier to get the screwholes lined up with the entire unit, it was easy to mark how it went in with a piece of tape before I removed it. Good mechanic- 45 minutes- me- 2 hours!

On the road again!... and fixed just in time for the fall weather.
This is my everday driver, 105 k and counting, and it's getting too wet out here in Washington for motorcycles!

Thanks again.
