My first XJ, it's a 1993. The wipers don't seem to swipe the whole windshield - moving to the driver's side they stop about 4-5" from side of the windshield, and swiping back they stop about 3-4" above the cowl - is this normal? I thought it was simply a pull off and reposition scenario but since they stop so far above the cowl it doesn't make sense. My intermittent feature doesn't work either, which I've read is a bad control module. Are these related?
