So I have been dealing with the P1271 code the last week, and finally had the time to pull the fan. Thought I'd take some pics since I never saw any with the issue. I've replaced the fan clutch a year and a half ago, so this harness may not be exactly the same, but the problem is easily seen.

For all of you that are wondering about this issue since there are a lot of threads, your not being lead astray. If you need help pulling your fan there are plenty of how-tos around, I just wanted to post some pics of the actual problem. Hope this helps out other wayward souls.

I'll add some pics of the fix as soon as I'm done.

Here is the harness removed from the fan..



Here is the damage



Pulled out the two damaged wires from the harness. Took my little flathead screwdriver and put between tab and connector (don't know if you have to do this but it helped :smile: ) and GENTLY pulled the two damaged wires out.



cleaned area and installed some heatshrink to damaged area's



Gently pushed pins back into harness



Installed back into fan, electrical taped and protected. I had to file out the opening to feed the wires in better. I'll post pics of that when they upload, my connection is really slow.
