The truck was in for other said problems and I told them about the flickering light on the mirror driver side and they told me it was wiring corrosion and that they will replace it. They replaced both mirrors even though the passenger mirror lights were working fine, but it made me so happy because I had previously broken the passenger mirror in a close encounter with someones trailer mirror parked halfway onto the highway as I passed them I was squeezing through oncoming traffic. I was very happy as these mirrors cost $600 from Chrysler.
