My windsheild wipers started acting up about a year ago. I can turn them on high and thats it. They wont turn off or work on intermittent. I have replaced the MF switch, Wiper Motor, and just recently replaced the gem module and sealed the windsheild. I have also checked the fuses in the fuse panel and the power distribution box and swap relays around. Nothing seems to work and I'm out of ideas. Any suggestions? or has anyone else had this same problem? Thanks,
