Hi all, iv just tried my rear wiper after 6 months off the road and it doesnt work at all iv checked the wires coming through the hinge in the tailgate and they are ok. Checked the electrical connection block for power and theres nothing getting through what else can i check and what no. fuse is for the rear wiper??

cheers in advance

Fuse is 6, relay is K9.
Any lights on the switch? Does the rear washer work?

I think they alos have additional relays are in the boot on the left hand side in the cubby hole where the tool kit and rear wash bottle are. They are probably for the rear washer but you could try checking and cleaning the connections there as well.
There are also two switches in the wiper gearbox, one for parking the wiper and one for the washer but they don't usually stop the wiper completely if they stop working.
Wiper Gearbox may also be full of dry grease and rust which will slow down and eventually stop the wiper. May even blow the fuse if siezed up enough.
