I have been searching high and low on this forum and haven’t found a solution. So before I get the patriot up on a lift and start searching into the great unknown if figure I’d pick your brains. Has anyone had he same issue and figured out the fix? I have tried many different ways to engage 4x4 to test it with no success. I currently have no check engine or fault lights. My model is a 2009 limited with manual transmission. I did see the 4x4 light once when I was rolling back in the driveway once so I am sure is not just the bulb. Also from what I can tell all fuses and relays are good. Trust me I have repaired a lot of things since I purchased the Patriot and fuses and relays were included. I figured once I got my tpms sensor light off by replacing one then the 4x4 would engage, but no luck.
