I've got a new one for you guys.
The weather just started to heated up around here finally, so I began running the A/C in my '92 K1500 (5.7). Well, she started overheating (220+) when running the A/C at idle for ten minutes or more. After going through all the usual diagnostics (compressor, fan clutch, etc.), I discovered the cause...
...the previous owner deleted the freaking condenser/aux fan and replaced it with the passenger side horn.
Yes, you read that correctly. The horn. They relocated the passenger side horn to right in front of the radiator, and removed the condenser fan altogether. Why they did any of this, I don't know.
But, here's my problem....the wiring and the correct connector for the aux fan isn't there. I have no idea where it is. Another condenser fan is only like $80, so I'm not worried about that. But I need to know which color wires I'm looking for (so I can maybe trace where they were cut), and what specific female 2-pin connector I'm looking for...so once I order it, I can wire it in.
There is a pair of wires in the passenger side of the engine bay, black and orange, that run back to the relay block, with an old corroded connector that wasn't plugged in to anything...but it doesn't reach the front of the truck where the fan is. So idk. There are no other wires or connectors that I can see that are unused/terminated/disconnected, but again, I have no idea what colors I'm looking for so that I can maybe start looking from the other end.
Edit: I also can't find the relay or the switch, and I need the mounting bolts, which do not come with the new assemblies and I can't find anywhere. Ugh.
Also, completely unrelated side question....has anyone ever had a bad TPS sensor cause an engine to straight up cut out/die, randomly, while driving? Thing died twice on me today while driving. No rhyme or reason. This is also on top of an occasionally rough idle/stumble that has reappeared. TPS is one of the few remaining things I haven't replaced and is our next best guess....as we've gone through a lot of other things to no avail.
Help! Lol.
