Wiper Module

---

For the past few years, my wipers would randomly stop working when in "intermittent" mode. To get them working, I would have to turn them to low
speed, then they would work for a random amount of time. Lately, I have to turn them to hi-speed to get the to work. I bought a new wiper pulse
board a while back, and finally got some time to get it installed.

April 2/2018


It got really cold last night. Woke up to frost, but apparently it was more ice than frost. Turned the wipers on, hear a "bang", no wipers. Being that I had
to get to work, I dried the windshield with some towels, and got on my way. I tried turning the wipers on several times, but they didn't move. When I got
to work, I shut the car off, then tried te wipers one last time. They didn't move, but I could hear the motor working. Nice. That "bang" must have been
the linkage arm popping out of place. Rain was in the forecast, so I scrounged up some tools and took a "smoke break". After fighting to get the wiper
arms off, I found the main linkage arm floating around. I snapped it back on and re-assembled everything. I did have this linkage disconnected the other
day, so I'm hoping I just didn't put it back together properly and it won't become a problem.
