I'm just a girl..
 

2002 Dodge Durango 5.9L 4x4. 2nd hand owner, almost 2 years no problems. Had a non professional hook up entire sound system, (I know 1st mistake). It worked great for about a day. when I turned it on something (fuse) blew because I lost all power to stereo, blew out interior lights and turn signals.Drivers and passenger window won't do down, Drivers door won't lock even with key. Also now the check engine, ABS, brake, and O/D lights are all on and I've disconnected battery, they still light up. I know these are not problems. I apologize to anyone for the I'm just a girl comment, but I feel like I've hit a brick wall here. I've checked every fuse, lights themselves, (I do have hazards). all seem good. I obviously removed entire stereo system. but need to get basics back, interior lights, turn signals etc. Thank you for your time.

Make the person that screwed up, pay the repair bill.Find a GOOD shop nearyou that handles electrical auto.Tell them all that you posted so they can get busy and fix.Even a auto stereo shop.Hope all goes well.............

Yeah that'd be 2nd mistake .
 

Found him on on CL Mobile Audio Installer, since disappeared

You are going to have to take it somewhere reputable and have them diagnose the issues.
