for short version read the bold below.
My wipers work some days, some days they don't.some times it works very slooooow.
when they don't work, i have tried different speeds, spraying the windshield, jiggling the switch and turning off the car and then back on. none seems to work.
I haven't ran any test b/c i didn't know where to start. obviously its not the fuses so my great troubleshooting ability makes me think its
d)maybe some sort of breaker or board that controls it.
I'm lost. are there common problems i should start with, i really don't want to start tracing wires?
