Heater blower motor 73 won't run

[Harmon C.]

Need some direction on what to do next to maybe save some time to do other jobs before leaving for regional. Blower motor did not run at all. After many tests I find I have No power at the fuse block. I run a test lead 12V+ to the feed side of the fuse and the system works. I need to know if I should tear into the fuse block or where the feed for that line comes from. I have a wireing diagram but I am not the sharpest knife in the drawer when it comes to reading it.I looked at a 74 harness I have and the two wires are orange and black at the back side of the fuse block.

Lyle on my 70 there is a another fuse in the engine compartment for the blower motor. This inline fuse is located in a plastic container that you just twist and unlock to remove the fuse. This may be for only highest blower speed though, I would have to check my service manual. Your 74 may have a similiar in line fuse.

Jim Yes that fuse is for the high speed and I know its location LH fender near the master cyclinder. I think the feed for the fuse is the ignition switch on the chart. Lyle
