headlights not working....

Check the two H-LP fuses in the under hood fuse panel.

Check the ECU-IG fuse in the under dash fuse panel.

I can't stress this part enough.

Oh nuts you already checked. Would a beefier fuse solve this problem? CT? I'm genuinely curious

NOOOOOOOO! Putting in a bigger fuse generally results in doing far more damage. Wires have a current rating and the fuse value chosen for a circuit generally is a function of the ampacity of the wiring and the maximum current draw of the device(s) on that circuit. Installing a larger fuse often results in exceeding the ampacity of the wiring, and if there is a direct short in the circuit, the now underrated wires will get extremely hot, possibly hot enough to melt their insulation and burn other things (or create more shorting points).

Agreed, i wouldn't think of using a larger fuse... and i did check to see if the bulbs are good, i can see both hi\low filaments, they are intact and the bulbs were less than a week old at time of origional post.

Thanks for the replys CT, but you were saying something about which wires to follow... if pictures will help i can have them on here tomorrow.

Pictures would definitely help. The wiring harness to the right side headlight is housed in wire loom for all but a few inches on either end, so if the problem is with the OEM wiring it is almost definitely on one end or the other of the wire from the fuse panel to the bulb. The additional wiring, that you mentioned, is more likely where the problem lies, so pictures of that would help.

Thx CT, i left my camera at home, so i'll take the pictures tonight and hopefully post them tomorrow.... i hate not having headlights!

Ok. So I am still battling this problem. The headlights come on now. But the driver side light is acting funny, both of the filaments are coming on and they are dim in comparison to the other one. Which works correctly. I don't know how it got to the state it's inn now. But at least I can drive at night. Any more ideas CT? Thanks again in advance

The H-LP/AMT Relay in the small relay box, on the passenger side, under the hood, may be sticking. You can try putting the HTR relay in its place to see if it cures the problem. The HTR relay is the center one at the bottom of the under dash fuse panel. The HTR relay is the same shape as the H-LP/AMT relay, but may have a different color shell. The two are identical though in function, so they can be swapped.
