I've got a 2004 Dodge Stratus SXT coupe that's in great condition. I recently installed a cd player and sub woofer in it.
I don't know if this has everything to do with the problem, but while I was playing music, turning it up, the stereo completely shut off.
Along with the cd player, the interior lights, sunroof and keyless entry were all disabled as well.
I've checked every fuse in the car and they all are still fine. I thought it may be a relay, but all those seem to be fine.
I was told it could be a ground wire of some sort, which seems plausible but there are way to many wires with no diagram.
My problem:
My radio, interior lights, remote entry and sunroof DO NOT WORK.
And my question(s):
1. Where can I find a reliable wiring diagram that may hold the key to my solution?
2. What else could the problem possibly be?
3. Has anyone else had this problem?
4. Should I just give up on trying to fix it myself and bring it in to get overcharged for a problem that may take 10 minutes to fix? (that was rhetorical)

 

Did you check the fuses under the hood? i believe there is a yellow one that controls the sunroof under the hood...

 

Yes, I checked all fuses inside the car and under the hood. All my fuses are intact and working.
It's not only the sunroof that stopped working - it was the radio, sunroof, interior lights and keyless entry.
If it were just the sunroof not working I could see it being the fuse, but it those 4 things that quit on me all at the same time, suddenly.
No other help??
