I have a 2010 Dodge Nitro. There are various electrical problems with this vehicle like not being able to lock or unlock the passenger side doors, both front and back, but I have a bigger problem which I feel is a safety issue. When my headlights are on, my left turn signal won’t work, but when my headlights are off, the left turn signal will work. I’ve tried disconnecting the battery to try and reset everything, but this doesn’t work. Any ideas before I take this into the shop and spend a fortune?
