Hello!

I am not very good with electrical systems, and I think I screwed something up. Looking for advice.

I was installing a new aftermarket horn on my 93 Pathfinder. So all the wires and the relay are new and separate from the factory horn wiring and relay. The factory horn and relay and wiring were all untouched.

Was having trouble getting the new horn to work (because I am a huge idiot and overlooked something). I decided to try testing the new horn by pulling the positive wire off the relay and touching it to the positive battery terminal (so at this point the positive wire to the new horn is directly to the battery, and negative directly to ground bolted to the truck) and this is when my power locks stopped working..

All fuses are intact.

What else should I be testing or looking for to get my power door lock switch working again?

I do have a spare 1991 pathfinder I can pull parts from if needed.

 

Day two. It has been raining, and the lock switch seems to have automagically fixed itself. Will update if dry weather changes that..

 

More or less it could be a simple loose connection. Check and clean all relay and fuse for any trace of corrosion with its contacts.

 

This may help in cleaning those contacts.

 

oh interesting lol!!
