Hi, I have a 2015 Dodge Dart. I recently changed the battery and polarities were opposite of what I am use to and hooked it up wrong.. I blew the blue 200 amp fuse on top of the battery but the car still started and drove normal. It lost power steering, all climate control and touchscreen capabilities. The check engine light, traction control and power steering lights are on as well. I replaced the fuse and still nothing is fixed. What else could the problem be? Thanks, Id really appreciate a quick and easy fix!
This may not be a quick and easy fix. Start by checking all of the fuses in the main fuse box and cabin fuse box. Replace any that are blown, and look for any other signs of electrical damage (like burn marks or melting plastic). Worst case scenario, you may have done damage to the vehicle's computer system. This would be most expensive and most time consuming. Rule out fuses first, as they are designed to protect the vehicle from these types of problems.
