My 91 500sl fan is kaput, or is it? I have checked the fuses, looked at the fan (it spins) cleaned it with electrical cleaner, etc. I have not removed it from it's home, and I am wondering if there is something else i can try before doing so.

Thanks![B)]

I'm assuming you are talking about the cooling fan and not the heater/AC blower. Try unplugging it and applying 12 volts directly to the fan (keep fingers and toes clear of the blades). If it spins you know it's not the fan motor and is most likely a bad fan relay.

Bad fan

Thanks, yes its the blower fan. Do you know where the relay for this fan is?
