[neminger]

i have a 89 240sx coupe with a digital cluster as well heads up display and my dash lights and digital speedometer works sometimes and then doesnt work alot of the time it doesn't i'm just seeing if anyone has any output on this or if anyone knows where i can get a new digital cluster any info would be awsome thanks

This is somewhat common I believe. There is a write up on here explaining how to fix it. I think it has something to do with the capcitors.

I have the same problem. Does it come on when its hot out or been driving for awhile? If so, its most likely the capiciter then.

yes mine does the exact same thing. when it's cold or i just turn the car on. no hud. then when it warms up or after a few mins it comes on.. so i fig since it does work it's really not a big deal or worth trying to fix(but thats just me)

Google it there is a HUD writeup. On another forum, but I think the original one he used was on here.

Electrolytic caps dont last forever and they use them for regulation. I would pull and inspect the cluster, replace the caps, clean all connections and give it a go.

Caps can be ordered from Newark.com
