I'm wondering if anyone has any experience with repairing the 89-93 GP HUD dimmer switch.
The problem: When it gets warm outside (~70 an hotter), the HUD starts dimming out until you can't see it anymore, and won't come back on until its nighttime and cooled down. My guess is that the contacts or something expand and lose contact inside.
Has anyone else had this problem? How did you resolve it? I have a (assumingly) good condition dimmer from the GTP, which has the adjustment slider intact. Is there a way to swap them without having to swap the tray and cable, which appear to be attached? i really don't want to take my whole dash apart. In any case, I need to service the HUD dimmer switch to correct the problem.
