Cleaned my radiators over the weekend

Where did you source your fans out of curiosity?

I went outside today to set up the manual fan high power override switch, both to have the option to cool the car and to test if the high setting works on the passenger side.

As I understand it, turning the AC on runs the low setting on the fan. And commonly the low setting will stop working when the resistor pack dies.

So I am hoping it's just my resistor that died.

Of course when I went outside to start this, I realized I had left my headlights on and killed the battery. First time in 6 years of ownership doing that. So the battery is now removed and charging on my trickle charger.

I don't recall... but it was an outfit that sells, in addition to other sports cars, used Porsche parts. The fans I purchased came from a newer Boxster/Cayman with !64K miles on them.

I had considered the resisitor as well then deciding to go with the lower mileage entire unit.

You can poke around some parts sites as well... best wishes.

Appreciate the info. I'll start my searches with used fan assemblies and go from there.

Last update to wrap up this saga for now.

I installed a manual fan switch, some pics below.

I definitely bought mini ATC fuse pin adapters instead of standard ATC, but I bent them and made it work. I secured them to the relay with a ziptie and used a connector. I can take better pics of the relay if anyone is interested.

Other than that, there is a pic of the switch location, ground location and wires coming from the relays.

The results were better than I expected. It's been 95+ here and I can keep the car under 200 easy with the high fans on.

They are most effective at slower speeds but they definitely make a difference at highway speed as well. I can keep the car around 190-195 on the highway at the hottest time of day. In the evening when it cools down I run about 185-188.

I would highly recommend running the manual fan control for anyone in a hotter climate.

I just ran my own ground and interrupted it with a high current switch. The smaller switch is for my USB charging ports that are connected direct to the battery with a fuse so I can run them when the car is off.
