My wipers keep stopping when on anything but high speed wipe? I have checked the fuse/relay box and taken out the red relay which I thought was for the wipers but they still wipe? I assume it is a relay issue but cannot find were it is!

 

it might be the contacts in the actual switch. i had this happen to me on an escort

 

Cheers will have a poke about with the switch

 

the track on the motor could be knackered,
when u use the fastest setting it jumps the gaps i could be right try another motor
