Fans wiring melting

[UmmScott]

Hey guys, for some reason my car doesn't like either the radiator fan or the blower fan.

The wiring at the connector to the radiator fan keeps melting/burning up and then the fan won't turn on. Ive already went to a junkyard and got a whole new fan and harness (the 95 harness was falling to pieces). When i put it in, the harness was like new. Now right at the connector the wires are bare and very crispy even with the new fan motor.

The same thing happens with the blower motor, only the burnt connection is at the inside fuse box. Ive spliced and have already went thru 3 fuseboxes from a junkyard because this connection keeps burning/melting.

Any ideas?

can u shrink wrap it or buy that plastic wire protecter stuff then wrap that in elect tape?

are you sure you got a good used fan:shrug: most I have seen are seized or sticking very bad .If the fan is drawing to much amperage to run it will melt the wiring .They actually had a recall on some early v6 fans for this reason

replace your fan

damn, this will be the 2nd time i will have to replace the fan... however the 1st time i got one from a junkyard. It works fine on high and low and spins freely... Could it just be getting old and drawing too much amps?

want SVT fans?

I installed a separate fuse holder next to my fusebox because the OEM one melted the fuse into the block. Problem is finding a fuse holder that has heavy wire to the posts. IIRC the fuse is 20 amps? Needs 10 gauge or better wire and a good HD Scotch lock. First holder melted till I found a good HD one. I ran the blower for a long time to cool the car down and the charge was good. I discovered the pressure switch below the battery was short cycling. I jumped out the compresser relay to make the compressor run all the time and the air cooled down real fast. The switch is on a schraider valve so it is easy to replace.
