Hi,
This weekend I finally attacked my lighting issues on my consule, its a 1983 240D. Fixed the connection on the bulb that illuminates my transmission shifter, and some other lights as well. Hoever, I took apart the temp control panel to fix / improve the bulbs that illuminate the circular knobs that control the heat /cold as well as the blower control. I found that the plastic pieces that holds the little bulbs were pretty messed up and that even a good cleaning and the use of contact gel didnt help. I then discovered that 2 of the 3 these plastic pieces pulled right out, 1 with the wiring still attached. I am including a picture. Whats the proper name for these and is this fixable? If fixable, how do I do it once I get replacements from the dealer?? At this time only 1 of the 3 circular knobs' lights work. Any help would be greatly appreciated.
Thanks!

I can't find a part # for that. MB of Richmond is closer to me, they are very helpful at the parts counter.
