1994 3000gt no constant 12v+. I checked all fuses and they check good. What could be the problem? Also, my power door locks stop working. I need help!
Check your negative connection from the battery to the frame and motor. They are known to get corroded. Remove the bolts and wire brush and clean surface.
These cars do all kinds of weird stuff due to bad grounds.
I agree with what dandyoun said and obviously check the battery posts/connections are tight and not all corroded
