A DIY alternative to a FBH perhaps?

Hi Cyrano.
I would not like to say as all I did as I was passing the car with it's bumper off at the time I took a photo maybe the member could tell us if he saw this post.

The current resistor on mine has the ends sealed with high temperature silicone sealant to prevent water ingress: and so far, over about a year and 15k miles, has been fine. A 100W resistor is well up to the job. The standard 50W silver resistor isn't, the designers (or penny pinchers) de-rated the component on the basis of it getting airflow to aid cooling - they did their sums wrong: resulting in a shorter life for the part. If you are going to go to the trouble of multiple resistors in a network and relocate them then you may as well look at designing a PWM circuit... The gold 100W resistor is fine when correctly fitted and sealed.
I'd say my gold one blew for the same reason, water ingress

The earlier 50W resistor was actually uprated to 75W - but that didn't work either.

Ok. Signed in. Sorry, the images are blurred. I've cleaned my glasses, so it must be the images. Any chance of better images, Roverlike ?
PS Are the low speed and high speed relays mounted next to the fan ?
