Rear wiper broken

Hi guys, hope everyone is OK!

Usual story here - rear wiper intermittant for a couple of weeks - now dead.

Thought I would check the fuse /relay before shelling out £300 for a new motor. Had a look under the dashboard and cant tell which fuse to check! (Mainly because it looks like my six year old might have a part time job wiring alfas... )

I've no experience with the 147 but i'd like you said check fuses, relay, cables between the bodywork and the bootlid using a multimeter and wiper stalk before buying a new motor...

Infact i wouldnt buy anything new untill you can pin point the fault.
If your going to change things i'd start with the cheapest and work your way up, fuse - relay and so on...
