Default HUD Dimmer slider

The HUD dimmer slider on my 94 SSE is broken. No matter the setting, the HUD display is always fully lit -- even when I slide it complete to the "off" position. Is this an easy fix?

TIA

It'* probably just an adjustable resistor. Look behind the slider and make sure that the wires are connected to it.

Does the HUD dim when you turn on your headlamps?

billha: How am I supposed to take off the trim? Do I need to remove the entire driver-side dash area?

uddyduddy121: The HUD doesn't dim at all. No matter what position the slider is in (even in the "off" position), the HUD appears full bright.

TIA,

I've never had the need to check the control on mine, but you should be able to see (or at least feel) the wires from behind the dash and push the connector on tight. If there'* other stuff in the way, you can remove the plastic dash trim panel and then maybe remove the mounting screws and pull it out to access behind it, but I'm not sure.

On my '92 and '93, the dash trim snaps off - there are a few metal clips that apply pressure to hold it in place. Tool companies make a special trim removal tool and you can use one of those, but I used my fingers and slight (careful) pressure with a flat-blade screwdriver.

I doubt that the potentiometer (adjustable resistor) would have failed completely, even if it was used quite a bit, so I hope it'* just a bad connection.

Actually it is also supposed to dim when you turn on the headlamps (regardless of the slider position).
