Rear wiper start/stop

[12ORY]

I need some helpful suggestions on an issue I am having with my rear wiper.

The wiper stops at random positions, and does not return to the rest position, when I have the rear wipers switched on.

When cleaning using the spray the wipers work with no problem.

I've tried lifting the wiper arm up to remove any resistance, and tried helping the motor on to prevent it 'sticking', but it does not help. I can hear clicking near the interior fuse box to suggest that it does not always have the same time delay but I cannot locate the relay.

Can anyone suggest what the problem might be; wiper motor or relay?

Where can I find the relay?

Wiper relay rear window, no. K91, Junction box fuse and relay panel, right front behind kick panel trim cover
MANUAL shows it as being bottom lefthand corner on the fuse/circuit board
