The high beams on my 2010 Ranger suddenly stopped working. I looked at a few different options and decided to buy a new switch off of RockAuto.com. That fixed the problem of my high beams not working but it caused my low beams to stop working. I was wondering if any of you might have any suggestions as to what the problem might be. Any advice or input is greatly appreciated and thank you in advance.

 

Welcome to the forum

New switch?
There are two
Main Light switch and Multi-function switch(turn signal stalk), and 3 fuses

Fuse 3 and 4 in Cab fuse box are for right and left low beams
These are powered by Main light switch when its on, but THRU the Multi-function switch, so test each fuse to see if it has 12v with Main switch ON

Fuse 23 in cab fuse box is for High Beams, runs direct to Multi-function switch so you have Flash To Pass all the time
23 also powers low beams but thru main light switch

And then there is the SJB(smart junction box), its the Body Computer, controls ALL the lights, Cab fuse box is part of the SJB, its behind the kick panel
