Fixing lights on 2001 Pontiac aztek as parking lights, tail lights and license plate lights do not work

SOURCE: tail lights and instrument panel lights out. all

how bout the brake lights if they are burnt out then the dash lights won't work thats to let yo know they are burned out.

SOURCE: Tail Light and License Plate lights stopped working

With light switch on, test the wires leading up to the mentioned lights with a test light(cost about 5 or 6 bucks at wal-mart) that way u can eliminate any corrosion questions and get to the source quicker, if test light indicates that the wire is hot, than check connection areas for any wear and tear and possible carbon corrosion. Check lightbulbs, my license plate light stopped working and wire was hot, but wouldnt turn on due to the housing base, got too dryrotted and wouldnt function propery, had to rig it up, but works now.

did you check both the fuses under the dash and the ones under the hood?

SOURCE: how do i reset service light on 2001 pontiac aztek?

Before you re-set it, take the car to AutoZone or other similar store to read the code. That way, you know why the service light came on.
Then AutoZone can re-set it for you (all free)!

== or ==

Disconnect the negative cable from the battery for 10 minutes, or more.
When you re-connect the battery cable, the service light will have benn reset. But it will turn back on eventually.

Hope this helps!

SOURCE: no power to tail lights or license plate light.

check the fuse with a test light on both sides of the fuse,
next would be the headlight switch.
