91 300SE heater blower question

1991 300 SE. I have searched the forums here and am quite pleased with the wealth of information. However I am at a loss because all of the things said to check here are fine. I checked the strip fuse it was intact but melted on one side. I touched it and it fell apart basically. I also checked the green/pink wire from ignition no power in on position. If I supply power to the strip fuse area viola fan works. I would consider that something may be wrong with the ingition but everything else still works. And when whatever happened it was like a fuse blew or something in the car and then no fan. Thanks in advance benz gurus.......Nate

If I'm reading the diagram correctly, the pink/green wire is dedicated to the blower. If it fails, it does not affect anything else. I'd start looking at the bulkhead harness connector and the ignition switch.

1989 300 SEL that mostly works, but needs TLC
