I have a Venture van that has an issue with the wipers that I can not figure out. I have replaced the crank arm (a linkage between the motor assembly and wiper linkage, if that makes sense) and the wiper module. Those repairs have given me a start at getting this resolved... originally the drivers arm was broken at the hinge (fixed that too) and the blades parked in the up position (common chevy problem) towards the A pillar. Now they park like their supposed to but they hit each other and only go about 2/3rds up the glass before returning and starting all over again. I don't understand this... is it the motor assembly, the linkage that hooks the wipers together and then to the motor assembly, or am I missing an adjustment... does that crank arm adjustment need to be refined? Your help would be greatly appreciated!
