Question type: Maintenance & Repair

I'm getting ready to go back through emissions
because my check engine light cause me to not
pass emissions.  I sent my dash cluster to a shop
to be checked and found out the check engine light
works in the dash cluster.  Now I'm trying to find
out whats my next move. I put the electrical grease
in the bcm and the ecm connectors still nothing.
The fuse works fine. Please let there be some
helpful inforation out there. Thanks

Unfortunately it's probably the PCM (Powertrain Control Module). The bulb in the cluster receives power (+) anytime the ignition is on. The PCM grounds (-) the circuit to make the light come on. Other than a bad instrument cluster, or bad wire coming from the PCM to the cluster, the PCM is the only other component in the circuit. You can check continuity through the wire that goes from the PCM to the bulb. Ruling out a wiring problem. Since you have had the cluster checked, the only other suspect is the PCM. HTH. -Jim

Do the pcm control the third brake light and info button also because they stop working too?

No. The PCM controls the engine and transmission. The brake lights and info button are most likely controlled by the BCM (Body Control Module). HTH. -Jim
