'97 w/ headlights but no parking lights??

just picked this one up from an auction for $500, runs good, a/c works, seems like a good deal. One problem though, it had no parking lights, you turn the light switch one click and nothing... two clicks and the headlights come on but still no other lights, no marker lights in front, rear, license plate, or even in the dash. Fuses look good and the relay clicks with the headlights, any suggestions??

Check the truck out for a trailer wiring harness, if there's one attached, disconnect it and see what happens. VERY common ailment on these trucks for the harness to short out, or go bad and cause lighting issues.

Report back. Welcome to Isuzu land...I have the same truck as you.

Keep in mind that the headlights and parking lights are totally different circuits.

Thanks for the welcome.
It does have a trailer harness hanging out under the rear bumper, I'll check it out.

Cat-fuzz, thanks for that info, I did not know that.
