$1200 Porsche Boxster - $10 RADIATOR FAN REPAIR! 

Ok, I am still confused even after reading the previous comments about the wiring. Others were confused too. NONE of the videos on the web showing this replacement clearly state what kind of wiring has which function. Somebody commented that the high-speed function does not work if one connects White with Green/White on one side, and green on the other side of the resistor. Is that true or false? And which wiring is correct to get BOTH fan speeds working? Thank you for the clarification.

Thanks. Gonna give it a try.

THANK YOU! I did the same repair today and it worked great. I also followed 'b" recommendation and uses a heat sink bought on amazon glued with heat conducting glue. I connected the green and the White coming form the plug to one terminal or resistor. The Green wire going to the fan to other. I installed the resistor mounted on the sink at the same location than the genuine one allowing the fan to cool it. It works great!

Great video. It's so helpful. Thanks bro!

Thanks. I tested both of my fans today because the high fans were always going on. I tested the high and low speed via jumping the relays and the low speed isn’t working so I’ve ordered two resistors. Hopefully it should be sorted. Thanks for the video

amazing vid just what i think o need as my left side is not coming on when up to temp

On close examination Porsche's "over-engineering" strikes again! The car is supposed to have low speed fans that come on when you turn on the AC or if the car gets a little hot. Then, high-speed fans when the car gets really hot. The way you completed your project, you now have ONLY low speed fans because you have both circuits (the green and the white wires) flowing current through the resistor. If you test the old resistor, you'll find a dead short between the green wire that goes to the fan and the white wire that goes to the high speed relay. So, the white wire needs be connected directly to the green fan wire for high speed fan operation. Those wires also connect to one side of the resistor. The other side of the resistor is connected to the remaining green wire for low speed fan.

that video did not help at all... you skipped all the most important parts.

This mod worked perfect. I did however slightly improved it by the following; After cutting the oem resistor, I used it as a heat sink and mounting surface for the resistor with a 1 1/2" hose clamp. The thought came after I compared temps from right (190 degrees and left (210 degrees) side. Left was the repaired side. After my improvement, right side was 190 and left side was 140 degrees constant. Btw wiring is green w/white stripe AND White to one terminal or resistor. Green wire to other terminal. Works like a charm!

Does this mod allow the fan to work on high and low speed? I did this mod and thank you very much for posting. Did you connect the green/white wire to the white wire and then on the other side of the resistor just the solid green wire?

Can you verify the correct wiring? Seems like the two green wires should be on one side of the resistor and the white wire on the other...

you want to bolt that resistor to something made of metal, as a heat sink, those resistors get HOT (that cable tie could melt)

Did you use 1 ohm or 0.5 Ohm resisters? Great video!

Help someone please clairify the wiring via diagram so i can wire properly first time..

Thanks again. I did this today and my fans now work on low speed and temperature issue solved. 👍🏾

Which colors of cables goes together to get the correct functions?

What size wire? Thx!

i like the dirty stp shirt

Wanted you to know that your videos (among others) helped me decide to shop for and buy a Porsche 996 911. And guess what.... I need to swap the resistor. I also wired up a manual fan overide switch for all the fans .

Performed this today and great fix!!! Are they likely to last long?
