Hello out there. My 89 Pathfinder's blower motor runs only on high speed. The factory wiring diagram indicates that one likely failure mode that would cause this symptom is that of the blower motor resistor. The location of the resistor is specified as "under the right-hand side of the instrument panel." Well, more than an hour of peering under the dash and disassembling the IP has not revealed anything that looks like a small bank of resistors.

So... Where the heck is the resistor assembly for the blower motor? How do I get to it? Thanks in advance.
