The climate control on my '88 300CE was working perfectly until suddenly it wasn't. Now the fan doesn't come on at all. I checked the #7 fuse and the fusible link on the left front fender and both are intact.

Before the climate control suddenly stopped, I had spent about 15 minutes removing and reinstalling the gauge cluster in order to change a bulb. I know this might be a long shot, but could I have disturbed something behind the gauge cluster which caused the climate control to quit?

Many thanks,
