240SX HUD to Analog done! But....

[Elbow]

Ok, well my HUD or digital speedo has never worked (89 240 coupe, KA24E), and my dash lights flickered and went off shortly after I got the car in December.

Yesterday I put in a analog cluster, and plugged it into my stock harness. The white to white black to black. My speedo works now, and my odometer works, it all works! Except the fact now I still dont have lights on the cluster or dash, and now my radio, or interior lights dont work.

The radio flashes on and off and the open door sign flashes with it. If I turn a light on, it wont go on at all, and the door open light flashes with it.

Any ideas? On both why my lights dont work and why I now dont have a radio or interior lights?

It is an aftermarket radio, and has always worked fine.

Thanks!

This is kinda of a funny thread. I remember my 240s...

well i read on nico that the plugs are not just color for color that the plugs need to be rewired so you might want to do a bit of reading on nico. THat might help.

haha, damn I am stupid a blown fuse made the lights weird and my radio broke, ALWAYS check twice!!! ;)

As for the dash lights, still looking, I have looked on NICO, ZILVIA, all those, have not really found exactly what I am looking for.

[Motormouth75]

Sorry have to ask did you check the bulbs? or what about your dimmer switch for the lights?

[Elbow]

checked bulbs, dimmer switch i havent, i'll check it. the stock harness was spliced for an aftermarket radio, could that have messed it up? lights worked when i got the car, then just...died... lol flickered, and eventually went off

[Elbow]

Ok now I might be dumb, but is the dimmer switch the ACTUAL switch where you adjust the lighting on the dash, or is it something else?

[Motormouth75]

yah thats the dimmer switch i have known them to go bad before.

[Elbow]

hmmm I will replace that, today I replaced the WHOLE knob like where the blinkers and lights, high beam all that is, only thing out of that was now both my lights work when high beam is on, before just one. So at least got something out of it lol.

Thanks though, I will try the switch.

[Elbow]

Well I put another switch in, just the switch as in unplugged it off my parts car and plugged it in, no go. Anymore ideas?

[ahmonrah]

punch the dash...worked for me.

using a dvm id check and see if youve got voltage going into the rheostat first, they are common to go bad

[Elbow]

what is the rheostat

[green91]

the dimmer control knob

[Elbow]
