The headlamps are controlled from the switch, body, and front module. The parking lamps have a relay but are also fed power a switched from the front module but the front module needs fused power at fuse 26 a 20 amp. Also fuses2 and 3 must be good. If you have an electrical problem, especially on the newer systems, you need a scanner to diagnose it properly. A technician always checks all the fuses with the key on so he does not have to run for a schematic everytime a different year and problem comes in. So make sure you read the section on testing fuses, buy a test light at the store and recheck, if all the fuses are ok, you'll need a controlling scanner which makes short work of electrical problems. Good luck, ok
