My fan has stopped working in my 72 240Z. All the fuses that I can find look fine, but I am wondering if I am missing an in-line fuse somewhere. I do have the fan switch removed (whew!) and was wondering if there was a way to test it with a multimeter. It has a plug with 6 wires attached to it (black, red, white in one row and green, white and blue in another row).

Thanks for your input and have an excellent Thanksgiving!

The Heater Fan IS powered through an in-line fuse away from the main fuse box. Look for a Blue wilre that turns to Red as it comes out of the in-line fuse holder (note, it could also be Red on both sides, this is a mis-leading item on just about every wiring schematic I've looked at.)

Testing the switch will take me a bit as I'll have to see if I have one handy.

That inline fuse case usually melts from over use. It should be located between the switch and the motor, and like E said, should have a red and blue wire or both of one color. It's a white plastic fuse holder and probably melted to the point that the contacts can't touch the fuse ends. You're best bet is to cut it out and replace it with a newer fuse holder.

It is exactly as described above, a melted in-line fuse. I tested the motor and it works fine. Once I cut out the offending fuse holder there is not much wire available before it merges into the main bunch of wires that are wrapped and inaccessible. There is a newer style fuse holder for the plug-in type fuses in my electrical spares, maybe I will splice that in. I will do some searches now to see how many amps the fuse should be. Thanks to both you guys for the tips!
