I am trying to use an aftermarket wiper switch but there must be something I am missing, unless I am mistaken there are only 3 wires and all are grounds, 1 ground links the other 2 grounds that go to the wiper motor to complete and ground circuits slow and fast.
Problem is the aftermarket switch will only support the fast mode and the slow mode just won't function.
Is there something in the stock switch that the aftermarket switch does not have like some resister or something?
Painless universal wiper switch is what I'm trying to use, I have a pic of the switch poles on my iPad but it's too big and won't post, I will have to get one onto my pc and post it.
Any ideas would be appreciated
