I got around to doing a little troubleshooting today and I wanted to at least shut off the aux. electric fans and heater blower motor, so I started with the fuse box. There are several fuses that appear to apply to the aux. electric cooling fans so I went down the list and got the following results pulling fuses.

1 - relay 1 aux. fan/engine fan term. 86... no change

3 - aux. fan... no change

10 - electromagnetic clutch and other functions... no change (This model does not have an electromagnetic fan clutch. It has a viscous fan clutch.)

2 - A/C compressor relay 2 aux. fan term. 86 and other functions. bingo, aux electric fans shut down. I reinstated 1, 3, and 10, and they stayed off.

The fuse box cover states "fuse blower motor outside fuse box". I see a couple of fuses that appear to be on the blower motor circuit on the wiring diagram, but the location isn't indicated.

I removed the cowl screen to see if I could find an electric connector for the blower motor, but it was not obvious. The motor is inside a case and it appears to have a cover that can be removed to expose the squirrel cages and motor, but I decided to research the documents I have before going further.

I'd like to at least get the blower motor shut off. I've got some short errands to run later this week and with the mild SoCal weather I can do without the HVAC system and it has a new engine driven clutch fan installed last year so the aux. electric fans won't be needed. About the only time they ever come on is the biennial loaded tailpipe emission test on the dynamometer.

Any help appreciated...
