I have a 2003 manual z
I was driving and parked the car and when I got back and started it gauge cluster is not working.
On the main guage cluster the only things that work are brake light and seat belt light.
That's it . and on the small trip cluster the tire guage doesn't work but oil and volts work.
Something strange when I have my head lights on the ac cluster and radio lights go off and when I turn head light off they come back on.

This is what I have done.
Check all fuses multiple times ,all 3 fuse boxes nothing
Checked to see if ac amp came loose no dice
Checked altanator and battery both good steady 14volts
Checked ground from battery to body hit it with sand paper.

Also my heater and ac work and mirriors work and interior lights work

Any help would be greatful. Thanks

I would pull ur "waterfall" apart and see first if its plugged in. Little white box with a ribbons like cable. That's a good start. U can plug it in and still have the waterfall off to see of it works

Thanks for the reply. I have already check for loose plugs on the unified meter ac amp.
Is there any diagnostic I can do on it!
