A few days ago, my speedometer quit in my 96 SI. Along with it, my check engine lite (MIL), SRS trouble light, trunk/roof/back window indicator lights, and cruise control all quit working. They don't even come on when turning on the ignition. I've checked all fuses (OK), replaced the instrument cluster (no change), changed the VSS (2 times), checked for bad ground(s) (none found), changed out the "dashboard wiring sub harness", changed out the "roof unlatched control module", and the swapped the ECM (I have a couple of cars for parts). Nothing seems to make any difference. Does anyone have any ideas or suggestions for things to check?

 

Speedo wise, definitely a sensor or the cable (depending on which model u got).
Every feature (except the SRS light) u mentioned, are all on the same FUSE. So i hope u just tried replacing the fuse anyway..

They're definitely all linked to one another in my car though (It's quite abnormal tbh) i think the old owner screwed mine lol.

With the SRS is it actually screwing up ? or just the light?

 

Did you ever get a fix for this problem? I have the same issue, my rev counter, speedo, clock and indicators don't work. I have light back light on the dash when headlights on and hazards work but as mentioned no indicators.
