Cab Lights Not Working

I have a 07 classic LBZ with smoke black Pacer Performance cab lights. About 3 months ago the lights started turning off and on when I started my truck. sometimes all of them would work and other times the middle bar would not come on. I Think there is a bad ground, but my friend told me that the middle bar might be bad. I haven't tried to replace the bulbs (I wouldn't think they would go out that quick). Can I change the bulbs without having to take the ceiling of my truck down?? I know they are sealed shut.

Any help would be appreciated,I'm new to the Duramax Forum

Sounds like either a bad ground or lose or dirty connector, if you slightly pull down the front of the headliner not hard just a bit you should be able to tell if its wet. My dad had the same problem they were leaking a bit and there was a bad ground. Hope it helps

I appreciate it. Im going to replace the middle bar it has a leak in there some where.

Niclockw..I have an Edge evolution on my truck, has your dad every had problems with
his fuel rail pressure? I got the error code P0087(fuel rail pressure to low) i replaced my fuel filter recently also. I don't run my truck on extreme a lot, I use the programmer for MPG. Should i replace the filter again with a better brand? I used the WSIX ( i think its a
lower end Brand but not sure)
