First Time user of this sight. Does anyone know why after dash lights don't work? Just purchased a 2005 Liberty and It has no instrument or dome lights when you open the door.It has had a different radio put in it and i have been trying to figure this problem out.All fuses and relays are ok
Well, welcome first of all. Second, what you've done here is called hijacking a thread. This thread is about changing the rear power outlet from a constant 12v source to a switched 12v. It is in no way related to your issue. It's considered bad form to hijack a thread like this.
That being said, you'll get more views, and even a possible answer if you create your own, new thread specifically about your problem in the General section. It may apply to the Electronics section if the issue is for sure related to the radio you have installed that is not OE.
You likely have an issue with the BCM (body control module). Whomever installed your non-factory radio probably messed this up. Others will probably have more specific diagnostic steps you can take to confirm this or test for other possibilities.
