I did the radio with the gm lan 04 cause it has factory amp and the bulbs came pre installed into a set of oem headlights assembly that my gpa bought for the car about a year ago

 

It might not be the ls I could be saying the wrong thing here but I will check those grounds in the pics u sent in a little bit and let you guys know what I find hopefully it's a ground issue

 

Does the valve cover have VVT on it? If so, it is a 2.4l not 2.2l.
I would pull the bulbs out to see what type they are, LED, etc. Strange they are not burning out.

 

I'm not sure off the top of my head but that's what I was thinking those are some tough bulbs lol

 

Just got done messing with it those grounds were corroded not to bad but enough to mess with it and the bulbs were high output so I put the ones that worked fine from my 07 in it and so far seems too work just fine

 

What is "high output"?

 

They were the Sylvania blue lights and the wattages was different than the regular headlights that came with the car so they sell oem headlight assemblys with non OEM lights they were drawing too much power

 

Weird, but you fixed it!! Awesome!
