My headlights are not working why?

Hi,

The headlamps may not be working for a few reasons. For example, a faulty switch, power supply, or the bulbs are bad.

If they all stopped working at the same time, then I would suggest checking power.

This vehicle has a totally integrated power module (TIPM). These are known to have issues with the connector pins for failure due to corrosion or breaking. What I would suggest first is to check for power at the headlamps themselves. If there isn't any, then test at the TIPM.

If you look at the attachments, they show the entire wiring schematic for the headlamps. I had to cut them in half to make them readable, but I did overlap them so you can follow.

Let me know if this helps or if you have other questions.

Take care,

Joe

My car runs great. It doesn't try to stall dead or anything like that. However, it does have one problem while driving. The headlights will turn off or flicker sometimes even the dash once they both went out and then came right back on.
Thank you for your time.

Hi,

If you look at the attachments below, they provide the fuse box orientations and what each fuse is for.

In addition to just checking a fuse, make sure there is power to it. A fuse may be good and not be receiving power.

I hope this helps. Let me know if you have additional questions.

The left light went out replaced with a new bulb and didn't work now don't have low beams on either side what could it he

If the new bulb didn't work, I'd check voltage and ground at the headlamp connector. Also, could be something going on with dimmer switch. Note the diagram. See the beam output, right/left, high/low. in the integrated power module, those wire colors are voltage. The ground for the headlamps is black.

There are trouble codes for the lamp circuits. Some of the national brand auto stores used to check codes for free. These are B type codes.
