Hi All, Just joined up, bought myself a 2004 4.0 TJ xtreme sport (which I believe is the columbia edition in the states) and on purchasing noticed the headlights were acting strange, there were no low beams, only high. Ended up needing a new multifunction switch which has been changed out and...

Hi there, I’m reaching out because I’m really desperate for some help right now. First of all, I know very little about vehicles, but this will be my third Jeep TJ, it is a 2000 Wrangler SE, four-cylinder. It has about 150,000 miles on it. I bought it about 5 years ago and have had to do very...

I recently replaced all of my O2 sensors (Thread: https://wranglertjforum.com/threads/check-engine-light-flashed-while-driving-recommendations.67087/) and felt like that had been successful. No new CELs, no rough idle, and no hesitation. However, at the time I didn't really watch any live data...

When I picked up my TJ it already had a pair of no name LED headlights on it. I finally bought a new pair of Axial headlights w/ DRL halos/turn signals. When I went to do the install they didn't function at all. I tried it 3 different ways: plugging the new light into the old EMC, plugging in...
