even though you are in the 87-91 section, please put your year and trim model in your signature accessed through your profile at the top right of the screen

sorry its a 1990 bonneville sse.
i have sinced updated my profile

Its a mystery, I had 89sse and now a 90 sse and both Dic lost communication ( no worky).Sometimes when its damp out my compass shows up.

Does your compass still work? Or has your compass been off and just now your DIC went out?

the compass has always been working, so had the DIC.
i loaned the car out and when i got it back i noticed it wasn't working.
because of this i really cant trace what caused it to fail.

If the compass still works, then either the DIC controller failed, or the screen failed on the DIC module. Does the DIC still beep at you when a door is open or you're low on fuel? Obviously you can't see what it'* complaining about, but you know that be-be-be-beep.

You said you replaced the DIC with a used one. Do you mean the module [Screen, thing you see on IP] or the controller? And was the unit you replaced it with working in the donor car? You gotta remember like 80% of DIC/Compasses don't work in our SSEs. However the common problem when BOTH compass and DIC don't work is in the compass module, which is the most common problem with the clusters. However I believe the second problem is screen failure, which I believe is what is wrong with my 2nd cluster.

thats what i was thinking. i sure as hell buy a used one if it was that.
