Putting my 92 back together after finishing a full heater box upgrade and I’m having intermittent bulb checks for the instrument cluster. I honestly never saw it come on before, but after putting the dash back together I’ve gotten it to work. Sometimes it works but most of the time it doesn’t. I know there a bulb check relay under the driver side lover dash, but does anyone have a trouble shoot or thoughts as to why it’s intermittent?


Good news is the heat works really well

It may be possible that there could be a pinched wire when you reinstalled the speedometer housing
Just a thought

Could be. I’ve run all the wires and I can see any clear pinch. I’ll try swapping out the really box next just to see.

maybe it never worked before and now that all connectors have been re seated it decides to work, or it had been disabled due the issue you have discovered and now it has been re enabled.
