86 560sl. Until yesterday, cold air. Replaced the fuel pump relay due to intermittent failure. In the process killed the radio.

Last night I checked the fuses and the radio fuse was out. All the other fuses were fine. Blower works, blows ambient air. Don't hear the clutch coming on and visual inspection shows it's off.

I looked behind the glovebox to see if I knocked anything loose but doesn't seem so.

Help would be appreciated.
