Folks, been a while, back for that great advice!

67 GTO w/ A/C

Blower fan has been quitting last few days.
Dash fuse is good.
old relay, had the Lectric repro in trunk so I replaced.
resistor is new repro from a couple years ago, looks good shape
all connections are clean, dielectric grease on spades.
30 amp fuse at alternator is good, made sure connection is tight.

I have power on grey wire everytime, can get the relay to 'click'. The dash switch and grey activator wire are good.
Fan runs, but without warning when driving, I notice it isn't working.
Back to garage, pull relay, put jumper from hot blk/org wire to brown wire, fans starts to run everytime, so fan is good. Put relay back, tight, grounded, clicks, sometimes fan works, sometimes it doesn't. When it does, it does not like high setting. Within seconds, it is kicking out. Runs OK on other 3 settings, but without warning will quit. Wont start again unless i take relay off, play with it, always have the grey wire clicking.
As before, if it quits, it doesn't usually start again, unless I pull connector and jostle things, may take a couple installs, then it starts working again out of the blue.

Wonder if the old, original A/C wiring harness is shot. My question is I don't know what would be causing the blower to quit. The 30amp fuse at alternator? It's a fuse, so surprised it wouldn't just pop, not "reset" if there was fan overload.

My next trick will be to jumper the hot wire to brown wire with relay removed, and watch it for a bit, go through the speeds. I haven't done this, I hate jumpering, get the fan going for 15 seconds, then pull my jumper off, I will leave it longer to see what happens.

Maybe that will tell me if connection is bad, or something getting hot. I see there has been some slight melting from years ago on the connector to relay, wiring overall and other connections looks good, no hot spots.

Simple as a pooched relay? Figured if it clicked to allow power to go through it, it would be good, but who knows. Not sure what the inside looks like on repro compared to the original, I have put the orginal back on, can't get the fan to run with it, but the repro will get fan going, just kicks out in 30 seconds or less, right away if on high.

Definitely will order new harness and relay, but would be nice to get this glitch sourced, as insanity is starting to set in doing the same thing over and over with same results!!

Thanks in advance, lots of posts on relay issues, but couldn't find one that was similiar problem.
