Maybe, just maybe someone might be able to help me here.
The washer pump was working sporadically, but now isn’t at all. The switch on the turn signal runs to a relay under the hood, and then on to the pump motor. Somewhere along the way it’s also fused.
If I swap relays out with a partnering one (same part) it still won’t work. I can remove the relay, take a paper clip and short the socket pins together and it WILL pump. So, it’s not the relay and it’s not the pump. I’m assuming that the fuse would be on relay side of things, not on the switch side, so again, I’m assuming it’s not the fuse.
Realistically it sounds like the switch itself, in the turn signal. But can a switch that gets used at low voltage and current maybe 50 times a year really be completely worn out past the point of ever making electrical contact again? The blinker gets used 100 times more often and it’s still fine. I even bought some spray contact cleaner and tried spraying it, but it’s really hard to get cleaner in through an almost non-existent opening.
Is there anything else I might be missing?
