ok so my cluster illumination lights, heads up display and odometer dont work. and no its not the capacitator thing on my hud because when i turn my key off it will flash. all my gauges work, all my interior, exterior, radio and dashlights work.

ok so heres what i have tried so far.

1. checked all the fuses and there ok
2. tried 2 different TCU’s (not the problem)
3. checked out the wiring and there doesnt seem to be any breaks or anything.
4. all the wires coming from the illumination switch to the cluster read 9.1V(should it be 12V? :/: )
5. the ground wires have 0 resistance.

dont know if this will help

Have you tried a known good HUD cluster in your car or tried your cluster on a car with known good wiring ?

If your down this way pm me - I have doubled and extended the main harness cluster connection which permits cluster testing (both types) by means of a second subharness allowing the dash cluster and a second one to function at the same time without installing it. ( all functions work but the fuel level is cut in half due to the parallel connection)
