A while back I swapped out the bulbs in the 4wd switcher in my '03 LE and ever since then my 4WD light has been on and my 4WD wouldn't engage but car drove properly. Many months passed by and I forgot about the light but recently I found time to get it looked at and bit the bullet and sent it to Nissan, log story short, they don't know what's wrong either and want to charge me an additional $140 to try and diagnose what's wrong. The mechanic was trying to tell me to sell the car because it's possibly an electrical issue.
If anyone has insight on this and could help point me in the right direction, I'd be greatly appreciated. Kind of at a loss right now
