I have 2 issues on my 1982 300SD:

1. The light that illuminates the buttons is out. How hard/how do you replace this bulb.

2. I get heat out of the vents but nothing toward my feet. I would much prefer heat at my feet as I am one of those who always has cold feet. No I haven't checked anything yet, I'm still gathering info. I'm assuming its a vacuum issue of some type.
