I checked the wires, good as new. Another interesting thing I noticed. If I
check the voltage on the wiper motor connector pins (with digital multimeter),
it is 10.65 V when the wiper switch is on and 11.85 V when the wiper switch is
I have found relays, there are three of them, wipe up relay, wipe down relay
and park relay, I did try to switch them around to see if wiper would work, no
luck, did not test the relays as such.
