Hi,
I just purchased a 1992 Nissan Sentra as a first car for my daughter. It's in pretty good shape overall, but it has a few minor things that need to be fixed. One of those things is the washer pump. It doesn't work at all.
In trying to figure out if the problem is the pump, or something else, I wanted to check to see if there was voltage present at the connector that plugs into the pump. I would have expected to see only 2 wires going to the pump (hot and GND), but there are actually 4 wires, so I'm a bit confused.
Can anyone shed any light on this? What are the 4 wires for? I'd like to be able to confirm that it's a bad pump before I go buy one. Any troubleshooting ideas?
Thanks,
Scott
