Help: Another Wiper Question
Did some searching but didn't find my exact wiper problem.
I've had my 89 XJ LTD since new and since new the Intermittent wipers have never worker as designed. On an 89, the wiper 'pulse' interval is continuously variable from approximately 30 seconds at the low end of the range to about 2~4 seconds at the upper range, except there's really no variability, i.e. the wipers will remain on a 30 second interval at any selection in the range except at it's upper end at which point the interval will be about 2~4 seconds.
Anyone else have this problem and know of a fix (aside from a new module)?

The wiper motor grounds at that crappy sheet metal screw on the driver's side front fender. Be worth cleaning.
