Please help. My headlights in my van are crazy. One is out on the day time lights and the opposite is out on low beam. Then the opposite is out on high beam. I have changed the bulbs, that did not work. Got someone to run wires straight to lights. That sent a signal to the computer, so that made everything go crazy. Inspection sticker expires end of this month. Please help!

Good afternoon.

The guy who bypassed the module may have damaged the headlight module as well as the body control module. Bad move trying to bypass.

There are fuses for the light in the module. Did you check them for power?

Okay, they need to verify powers to the light module as well as the BCM.

I would remove the bypass and hope there is no damage to the modules and have the wiring issue checked by someone who knows what they are doing.

You need to start at the headlight switch and work your way out to the lights. Tests for power with a voltmeter or test light are needed.

They need to follow the diagram that I sent you to find where you are losing power.
