I have a 2005 ford galaxy with slow wipers

Hey there. I had a similar problem on my 2001 galaxy diesel. On research it's a very common problem. If you are mechanically minded it can be an easy fix with a bit of time. You need to remove the whole wiper linkage and motor and free out the bushes that hold the wipers in position applying pbc grease before refitting. Continued use will only result in your motor burning out which is 350+euro from ford and if the linkage seizes completely then another 400+euro so catch it before it's too late.
