About a year ago the key fob quit unlocking my discovery 2. Then last month my fan blower quit working which ended up being a blown fuse. Right after I fixed it the window wiper motor quit working. I replaced it and checked the fuse. Could all these things be because of a bad fuse box?

 

Could be but I would clean all the grounds first. I took it one step further and daisy chained a wire to every ground point under the hood.

 

It sure sounds like it.

FYI: A bad fuse box is somewhat easy to diagnose because you will always see signs of water ingress (green stuff) inside the fusebox once you remove it. Rarely in my experience does a fuse box go bad without water ingress or the subsequent visible signs of water ingress.

Fuse box is under drivers panel though. This could in theory be water getting into your passenger kick panel area ie BCU/ etc. Check there as well for signs of water damage on electronics.

First question: Do you have water getting into your disco?

 

Could be, but it is a 20+ yo Land Rover not really known to be reliable after 100k plus miles.

 

@Extinct I am just short of 182000 miles still reliable, but stuff is wearing out 21 years is long time
