Autozone has a webpage with instructions on how to access the wiper motor on my 1988 truck. The wipers stopped working last week, and I figured that the system couldn't be that complex. Plus I could hear the wiper motor running, so I figured it might be just a broken connector of some sort. So today, armed with Autozone's instructions, I removed the "cowl" ( a narrow strip of metal between the windshield and the hood that I didn't even know could be removed) took some other stuff off and found the problem -- the arm that connected the wipers to the motor had popped off. So I put it back on, tested the system and then put it back together. G was helping, and when I got done and turned on the wipers, the passenger-side wiper kept screwing up. G kept talking about the loose weather-stripping around the windshield, but I wasn't interested in the aesthetics of the truck. So I kept cursing the wiper and trying to seat it so it would work, and G got louder and louder about the weather stripping until he finally got through to me that the loose weather stripping was hanging down to where it kept knocking the passenger-side wiper blade out of position. I couldn't see it when I was in the truck running the wipers. I'm so glad that he was there helping -- it could have taken me days to figure out the problem. Hooray for Autozone for having comprehensible information on how to repair ancient trucks! Hooray for the Internet for bringing that information to me! Hooray for my dad for teaching me how things work! And hooray for G for figuring out what the root-cause of the problem was!
