Wanna have some rainy day fun? Try changing them!
My first real DIY. Changed the oil fan resistor. Somewhere it was described as a PITA. There's a reason why the labor is so expensive. I would say its a major PITA to do it by the book, but . . . that said, it took a couple of hours, mainly just from unloosening the wrong bolts and tightening them back up, trial and error, and a few searches on Rennlist, Pelican, and P-Car and, job complete. The car now runs markedly cooler. Actually like night and day. Fun to see the results.

Whoa!
Just did mine yesterday ....coincidence?
Have to agree that it's a major PITA!
Take off wheel, remove fender lining, remove headlight assembly, remove lower bumper cover, lower oil cooler, remove first plastic nut on cover plate, swear and blaspheme about remaining two nuts, spend 1/2 hour touring parts shop for 1/4 inch driver extension and flexible drive, go home, remove last two nuts, remove cover plate, spend two minutes replacing resistor , screw and bolt all stuff back together.
Spend 3 hours on two minute job.... Finish just before sky turns gray and threatens rain.
Retire to sofa and
PITA but now done

I spent Sunday afternoon doing the oil fan resistor. I'd limped along for a month or two using my high speed fan switch to manually keep temps in line but finally had the time to change the damn thing. Definitely a PITA. I got sick of fighting the cramped space and pulled off the bumper cover. Once I did that, it was easy. It was a bit of a pain to get it back on, but less hassle than it would have been to keep it on for the replacement IMO. (It's easier to do the cover once you've done it 3 or 4 times.)

Thanks FO3! It was fun. And congrats to Tom W and germanxtc. Well, today was the Air Conditioner Resistor. Now, for whatever reason for me, the oil fan resistor was glaringly more to work with but . . . damn, that AC resistor was a real beast, tucked way back there and, I forgot about the allen wrench part (noted on P-Car/Robin's site) AC requires it, oil cooler fan does not. Duh . . .! I spent the first 1/2 hour trying to unloosen the welded on nut! Anyway, it is done and the nut is still welded in . . . the air is crisp and icy and the car is back together. Bottom line, once you get a little familiar with the space, doing it by the book per the origianal factory placements probably takes less time than the improvised fixes. After the learning curve, I could now probably do either in about thirty minutes.
Glad that is now through. I am with Jauder . . . that plastic is PITA to get seated properly. So DIY's for winter quarter 04 are done: Fabspeed Supercups installed, vacuum valve replaced, both oil fan & AC resistors replaced, AJ USA aluminum pedals, and spoiler curtain/wall replaced. Had a lot of fun and learned a lot about my car as well as patience!
Early 05 were talkin' brakes, lines, rotars and flushing. Hopefully big and RED! And thanks so much to the tireless John D. who makes this place such a wonderful and informative resource. I would have never taken a stab at working on my own car, much the less a top of the line Porsche, were it not for Rennlsit and the posse I have met over the past five months. Have a great New Year celebration everyone.

I did mine when I did my front bumper cover respray.......I agree with everyone else, the bumper cover being off didn't make much difference. The job is a true PAIN, my biggest problem was my hands, there kinda' big, that was the killer for me. It would be much simpler if you know a small child with small hands .
