The rear windshield wiper of my '76 245 wagon is bust somewhere along the line, with the most likely problem residing with the switch itself; I've confirmed the motor to work, as well as replacing all of the tailgate wiring. When I first got it last year and had it inspected in my home state of Massachusetts, it passed inspection on all fronts. However, this year, it failed with one of the citations being the failure of the rear windshield wiper. When I went to a mechanic to verify that another supposed point of failure- the tie rod ends- were fully compliant, he suggested that I just remove the blade and leave the nub or remove the nub entirely and just put in a delete plug for the time being until I get around to fixing it. Which would be more advisable? I've never felt any loss from not having a rear wiper, but I also would rather not fail inspection again. Should I just remove the blade, or the whole thing entirely? Any feedback is most appreciated! Thanks!
