The owner of this 2010 Ford Mondeo Zetec TDCI 140 had replaced the headlamp control module fuse at least four times now and had just exhausted the small pack of 5A fuses he had purchased to replace the original fuse number 43 in the under bonnet fusebox.
It is normally the case that when a fuse blows it will be due to a looming problem and is very rare for a fuse just to blow because it is worn out.
Realising that action would need to be taken the owner bought the Mondeo along to see if I could discover why the fuses kept blowing. My first action was to unplug the adjusters on both headlamps, this did prevent the fuse from blowing and so I knew I was on the right track.
Plugging the nearside adjuster back in immediately saw the fuse blow again, just to be sure I then unplugged the nearside adjuster and plugged in the offside, with the fuse staying intact I was sure of the problem.
With the new headlamp complete with levelling motor ordered up and fitted, the fuse no longer blew and the Mondeo was ready again for the dark nights.
