On day 1 of owning this car I noticed the blower runs all the time when fuse 36 is in place, so the resistor is likely water damaged.
I also spotted the scuttle at the base of the screen was loose, likely allowing the water ingress and damage.
This video is about fitting the scuttle. The blower repair will be in a later video.
I’ll be swapping the screws for the right ones in due course.
