89 240sx taillight and gauge cluster issues

[wild7driftboy]

My taillights, license plate lights and gauge cluster lights aren't working, I checke the fuses already all are good, my bro thinks it might be the light switch since we've had issues with that in the past anyone have any experience with this?

The taillights and gauge cluster lights are both on the same fuse. Since they are both out, I would double check your taillight fuse as well as the contact points in the fuse block.

Also check the tcu which is the white box below the drivers kick panel.they burn out over time.

I had the same issue and this was my problem. Pull it out and open up the white box and see if you can find a burnt spot on the circuit board. I went to a local junkyard for a new one and it did the trick.

Checked all fuses changed bulbs checked main fuze everything, think it can be the lever for the lights?
