Dash and Parking lights out - 2001 ZX3

I have a 2001 ZX3 and the parking lights, instrument lights and interior light has stopped working.

I checked all the fuses (under the dash and hood) but nothing looks bad. I found a posting in another forum about the rear licence plate light being corroded and causing the problem. In my case the the lights were corroded so I took them out and cleaned them up and put new bulbs in, but its still not working.

Anyone have any idea where I should look now?

Thanks,
Steve

your giong to have to recheck the fuses with a test light or a lighted fuse tester. if you still have a problem then try checking your dimmer swich
