I have a 87 wagon (GL) on which the intermittent wipers stopped working. They also do not return to the parked position at the bottom of the windshield when you turn them off. Any ideas? Would the bad switch be in the steering wheel column or is there a relay hiding somewhere that I didnt find? Not that I'll need the wipers soon... it hasnt rained here in Seattle for months! Thanks in advance.. Collin
