Just started having the following issues with my 2008 Kia Sedona. Lights come on now when the van is cranked up...even with the switch still off. They only work on low beam now and not high beams. Also the wipers will not park automatically when turned off, nor work on the intermittent setting at all. noticed also that the E-brake light is always on now even with the E-brake up/disengaged. Is this a turn signal switch issue? Does the switch control all these functions? Cheapest place to get a replacement part? Auto Zone is $119. How labor intensive is the job? Thanks in advance for your help.
