The interior rearview mirror on my 1999 230SLK started to leak a few weeks ago - showing the dreaded lava lamp bubbles. I had read several posts here about others with this problem who bought new mirrors (about $180) and did the replacement themselves. I turned my mirror around and found out that is was made by the Donnelly Corp. and I tracked them down to Holland, MI. After a few calls I found their Quality Assurance person in charge of "leakers". Had a nice conversation with him and bottom line was as follows: I had to fill out an on-line warranty claim form and attach two digital photos. In a few days I was told that a new mirror was on the way and I needed to send the old one back ( the numbers for Donnelly's FedEx and UPS accounts were provided so this cost me nothing). The new mirror came and it is an exact replacement for the old one. I installed it using the instructions I found in the archives on this site, a 20 minute job. So, if you have a Donnelly mirror that has gone bad you might want to call Mr. Heath Flanery, Magna Donnelly Corporation, 616-786-7495 and see what he can do for you.
