Rebuilt Cluster now no back lights ??

[bayareadude84]

Had the IP cluster on my esky rebuilt all new bulbs new step motors new info display circuit board EVERYTHING !! and now the back lights dont work ?? @ night the cluster dark no lights at all. Previous night back lights were working fine ??

Tried to test with new dimmer switch and nothing ??

Cluster guy SWEARING up and down its not the cluster "its my truck that has issues"

I did replace radio that same day with a aftermarket Chinese head unit and crux bose interface, But don't think it has anything to do with it ??

Turn on the headlights and check for 12 volts on the red wire in cavity A11 of the cluster connector. If you have power there and the cluster otherwise is working, which indicates that you have a good ground, then the cluster is the only other possibility.

BTW if the instrument panel dimmer switch is not at its highest setting, then the voltage will be somewhat less than 12 volts.

Try the dimmer switch in multiple positions to be sure. Check your fuses too. Test light might be easier for this, and yes your new radio could contribute. Unlplug radio harness. Eliminate variables one by one.
