So apparently the multifunction switch on my jeep is short circuiting and making the left blinker to go on and off at random times due to a little water and mud (had that figured out by the dealership for $150), next they wanted to swap it for me for $360something. I was too much in a hurry and luckily declined and later on found the switch online for just 32.99!!
So 1. I'm never going to the dam dealership again and 2. How easy is it to swap the switch? I plan on doing it myself if its real simple.
