I have been searching for an hour or so here & cannot find info needed. Perhaps I am not adept at finessing this board. Today my 87 244 wipers came on when I turned them on, but will not go off. They stopped a couple times with the switch left in the off position, but as it was raining & I needed them, I would bump them back on & turn the switch back to "Off"..Now they no longer will stop unless I manually hold the control arm in a certain position..I have built a "Rube Goldberg" tie-off to loop over the arm for the near term..So Can I assume this is probably a bad relay? Where do I find that relay to buy & where is it located on the car? Thanks in advance! Mike
