Hey guys, I recently purchased a '99 Wrangler Sport and am absolutely loving it! However I'm noticing some little problems are starting to pop up. The check engine lights keeps going on and off. The code is for the rear O2 sensor, P0138 or whatever, so I'm going to replace that soon. Today I realized though that my front passenger side lights don't flash when I turn on the cautions. The front and side turn signal lights. They work perfectly fine when using the turn signal however. Also, only the left turn signal indicator flashed on the dash board when the cautions are on. Anyone have a clue as to why this could happen? Some loose wiring maybe somewhere? It's not a huge deal but here in Chicago I have to use my caution lights occasionally when parking so I'd hate to get a ticket for it. Thanks in advance for any help!
