Mein Auto: 1993 740i
93 740i - Where is the resistor for blower?

Can anybody tell me where the HVAC blower motor resistor is. It's also called the FSU in some places. My heat/AC blower motor does not work and from all the forum and i'net searches I've done - it points to the resistor. Many places have good instructions but none for my car model.

I've hooked 12V straight to the blower motor and it works fine so I know it's not the motor. The dealer doesn't know where it is either but they described the replacement part to me. Sheesh!

I've gotten to the motor through the firewall in the engine compartment and tore out the glove box so have access to all that area and can't find a thing.

Can someone tell me where to find this thing? Thanks for the help.
