A/C Fan Quit, Argh!

[mrvette]

DID YOU do anything with the starter/bellhousing recently??? if so, there is a wiring error, there is a black ~10 ga wire with a 3/8 loop on it, it goes to GROUND, as in engine block somewhere, and NOT the battery cable.....it is the ground wire for the blower, wiper motor, and relay......

that would explain the back feed light on your dash....

common error, and so I did it too, years ago, when that happened, I relocated that damn wire to up top on the intake manifold, no more of that shit....

:cussing::rofl:

No, have not done anything in that area. BUT, I have not looked in that area either since this problem has come up. All those wires are dang close to the header on that side, could very well have got hot and fused together.

Thanks, gives me another spot to check.

I Love working on engines, bodywork, painting, etc. Trouble shooting electrical sux. :hunter:

I"ll swap you body work for electric, anyday......:shocking:prrtt:

Update

Thanks to all you guys for the help. Been soooooooo busy but finally got time to finish this thing up.

Put in the new relay, found of couple of the old plugs were a bit corroded cleaned and tightened up, as above, installed the new fan, etc.

It works! Appeared to be the fan and relay had both went out, one killed the other??? Or the ground now having 12 volts on it??? I gave up chasing ghosts and grounded the fan directly to the battery and all is well. I will purchase a fire extinguisher to install in car just in case.

One big NOTE to self! If your voltage is below 11.5 while working on this stuff, the high speed fan nor the AC clutch will kick in. Thank God found this out by accident before chasing my way around again. Attached charger as battery was getting low.

Thanks again to all for the help!
