I have a 2013 XLT EL that I have been having strange electrical issues with lately. It started with the rear wiper being erratic so I replaced the rear motor, lubed the wiper connection through the window, but it didn't fix it. I then replaced the multi function switch on the steering column to see if that was bad, it didn't fix it. So I simply disconnected the rear wiper electrical connection to prevent it from possibly draining the battery. Now the windshield washer pump stopped working on me, easy fix, bought another pump, installed it, and that one doesn't work either. WTF. I checked power to the washer plug, good 12v, I then took the original pump and powered it with a battery pack I have to see if it works, sure enough, it spins right up. So I know the pump is good, I have 12v at the plug, so why does the pump not work now? I'm thinking maybe a grounding issue somewhere that is tied in with the multi function switch or something? Maybe that's why the rear wiper and now the pump are not working as they are controlled by the same multi function switch. So, does anyone know what grounds I should be looking for that run these systems? Thanks for any help as this is getting frustrating.
FIX...So I went back and thought about what is going on and what I did previously, as I stated earlier I disconnected the rear wiper motor to prevent it from getting stuck half way and possibly draining the battery. I plugged the rear motor back in and now the washer pump works! I assumed that it would still work even if the rear motor is disconnected, but nope. Not sure why it would stop it from working even as I was getting 12v to the pump with it disconnected, but this fixed it.
