Best Answer

Had the same problem with one several years ago. First, check out the fuses. If those are ok, turning everything off for about two minutes and then back on again will sometimes work. If that doesn't do it, try your nearest Nissan dealership. Those digital instrument panels are maddening.

Answer #02.

What i did when the digital dash went out on my 1984 300zx may work for you. Mounted just to the left of the radio and to the right of the steering wheel column, there is a silver box about the size of a paperback book. You have to remove the lower cover that is underneath the steering wheel and held in by about 4 screws. If you tap on the small silver box with a screw driver or something like that, the dash should come back on. Do it while the car is running. I actually sliced a small opening in the plastic cover so I can just tap on it without removing the cover every time. You can also remove this silver box or open it and re solder the loose parts.

Answer 3

The digital dash and rear windshield wipers run off the same wire. There could be a short or loose connection that runs down the drivers side inside the panels back to the rear windshield wiper.

Why does the digital dash cluster not work on a 1987 300ZX turbo?

One of the most common problems on the first-generation 300ZXs is the digital dash power supply unit. The part is like an electronic module, located under the dash on the driver's side. The internal cold solder joints wear out, leading to failure of the power supply, and therefore no digital dash lights. It is quite possible to re-solder those joints yourself and get it working again. Another option is to search the web. Look up 300ZX digital dash power supply, and you'll find people selling them reconditioned. Others offer the service of refurbishing your old unit if you send it in. If the power supply isn't the problem, then it could be the digital cluster itself. But more than likely, it's the power supply unit.
