72 240Z Light Problems

[mikeont240Z]

Hi to all - lost lights without blowing a fuse. No longer have dash, tail, parking / driving (side and front), licence plate lights. Headlights, signals, brake and interior lights all work. Any suggestions on what to check - thanks in advance, Mike

 How do you know you didn't blow the fuse? Did you check it with a meter? 

Do you have the correct bulbs in for the side markers, turn signals and tail lights?

Inspect for corrosion at the side markers. That will come into play later.

Thanks - everything has been working fine for the past few years. Correct bulbs in lights. Have not checked with meter but will do that. I'll also check the side markers a bit better.

Also, check the 6 wire connector under the dash, specifically at the green/white and green/blue wires. Those are the ones that the parking light switch connects.

The reason why I asked about the bulbs is that it is easy to replace the stock bulbs with 1156 and 1157 bulbs. While those bulbs will work in the sockets, they draw more current than the 67 and 1073 bulbs specified by Nissan. The extra current can cause heating at connectors with that one (and the fuse box) being the most vulnerable. The heating can cause damage without blowing the fuse.

Thanks again - I'll have a look at each bulb when I check for corrosion. I didn't know to check the 6 wire connector and will do that first. Will post when it's figured out - thanks again!
