2005 chevy trailblazer 4.2l 4wd 160000
Fuse box fuses under hood are getting power to the fuses for the headlights low and high. Most of the other ones don't have power going to them. I noticed this problem because my low beams are not working and I checked the bulbs they are good. I did take my truck to somebody and they put a scanner on it and the check engine light has been on since I bought this and the codes were evap system small leak large leak and coil misfire.
I'm sure the engine is 4.3L but close enough.
try swapping the headlight relays. Other wise it's going to be bad wiring, corrosion in the sockets, bad grounds etc.
Theres a gm 4.2L, its an inline 6
Thanks. I know about the 4.2
I got it confused with the Chevrolet Blazer which has the 4.3
