73 truck with pretty much the same problem as in this thread:

https://board.moparts.org/ubbthreads/ubbthreads.php/ubb/showflat/Number/2588526/Searchpage/2/Main/214707/Words/%2Bblower+%2Bmotor/Search/true/blower-fuse-overheating.html#Post2588526

In doing some wiring repair on this truck under the dash, I ended up running new wire coming out of the steering column ignition harness; the black power wire had been way hot and brittled up both connectors. I ran the ignition harness blue wire (Accy) to a terminal stud up under my dash on the firewall. I then ran the blue wire from other side of this connector, which runs under the dash to a welded splice and then on to the fuse box for Accessories, to this new terminal stud.

My problem; at the fuse box location for fuse/power to the blower switch, I had already replaced the toasty end fuse holder/clip with one out of another harness that was in a little better shape, and it's held up, but with the plastic melted away, I'm a little worried about it vibrating loose and heating up worse. Any reason I could not safely run this power wire for the blower switch to my new terminal stud for Accy power, putting a 20A inline fuse in between the stud and the switch?

Thanks,

Joe

I did a very similar thing on my 1972 W200 for the same reason.

Thank you, 6PB! I will be putting this on relay(s) in the near future, but that still won't address the fact that the power wire from the fuse box to the blower switch itself is still sketchy, even if relays are taking the load off that switch.

Regards,

Joe
