Hello!!
Hey, Galahad, did you ever come across something like this?
I replaced the 25A fuse with a 30A one because it blew up a couple times. Worked like a charm for some time, but today I looked at it and it was melted :(
I do have a somewhat modified auxiliary fan, in that it's the OE fan (I opened it and lubed it), but in parallel of having the AC and the 2 thermometer switches in the radiator, I also have in parallel (to the high speed switch) a relay that's controlled with the ECU so that it turns on if the temp goes above a certain threshold.
thanks in advance for any feedback :)

Juan - we haven't had someone with this issue before. I have some ideas, can you email the support account so I can assist? Include photos of the wiring for F17 on the inside if you can, I'd like to get to the bottom of this.
