Wiring problem

I have a 08 cobalt,this car was in a accident before I bought it and caught on fire after I bought it . The dealer found that it was not repaired right and put a new wiring harness in it. All was good, now the front speaker,the directional sound and door lock chaim don't work. I looked in the fuse block for loose fuse or connection all was good. I got under dash and checked as many connection as I could find, all looked good. Does anybody have a idear.
Thanks,
Rick

"this car was in a accident before I bought it and caught on fire after I bought it . "

That about says it all......it's obviously a wiring problem or wiring problems.....could be anywhere......you would have to get a schematic of the systems affected, and trace out each circuit.....

Good morning Rick,
I'm sorry that you're having some electrical difficulties with your Cobalt at the moment. If I can look into this further for you, please send me a message here on the forum with the last 8 digits of the VIN.
All the best,

I realize I'm a little late to this party, but WOW my car is doing the same thing. left front speaker,and turn signal audio is intermittant....mine seems to be influenced by temperature, if it's cool thing work OK, and when it's warm outside they cutout and don't work as they should.
Did you find a fix for this??
GM customer service....could you provide any insight??
