Symptoms / reason for repair

Dash lighting may be dim, inconsistent, or unresponsive.
Old contacts can get dirty, oxidized, or cranky.
The dimmer wheel or switch may feel scratchy or uneven.
Cleaning the switch is cheaper than immediately assuming the whole dash is cursed.
The wagon deserves that cozy green 1980s dashboard glow.

Supplies & materials

Electrical contact cleaner: made for switches and contacts.
Plastic trim tools: because old interior plastic deserves respect.
Microfiber cloth: for dust and fingerprints.
Small brush: optional, for dusty edges and switch openings.
Painter’s tape: for labeling screws and trim locations.
Patience: required, because dashboard plastic loves drama.
Tools

Equipment for tiny electrical archaeology.

Phillips screwdriver
Small socket set
Plastic trim removal tools
Electrical contact cleaner
Flashlight
Phone camera for documenting screw locations
Small containers or bags for screws
The emotional strength to not force brittle trim
Interior plastic rule: no yanking. If something does not want to move, there is probably a hidden screw, clip, or tiny Chrysler riddle involved.
Step-by-step

The glow-control plan.

Step 01

Disconnect the battery.

It is a tiny electrical job, but safety gets to be boring and correct.

Step 02

Photograph the dash before touching anything.

Take wide photos, close-ups, screw locations, and anything that looks like future confusion.

Step 03

Remove the trim carefully.

Use plastic trim tools and slow pressure. The wagon is vintage treasure, not a parts-bin piñata.

Step 04

Access the dimmer switch.

Find the dimmer control, check the connector, and inspect the surrounding area for dust, oxidation, or loose wiring.

Step 05

Spray contact cleaner carefully.

Use short controlled sprays, work the switch gently, and avoid soaking anything that does not need a cleaner bath.

Step 06

Let everything dry fully.

Contact cleaner evaporates, but give it time before reconnecting power and testing.

Step 07

Test the dimmer.

Reconnect the battery, turn on the lights, and check whether the dash glow responds smoothly.

Step 08

Reassemble gently.

Put everything back in reverse order and celebrate if the tiny wheel of glow behaves itself.

The goal is not to modernize the vibe out of it. The goal is to make the original weird green glow behave like it still has responsibilities.
Photo notes

Dashboard evidence.

Biggest risk

The real enemy is old brittle trim, not the switch. Going slowly matters more than trying to finish fast.

Final result

TBD. If cleaning works, the wagon gets smoother dashboard lighting. If it does not, the investigation moves to bulbs, wiring, or replacement switch territory.

Bring back the glow.

Tiny switch. Big dashboard mood. The wagon deserves cozy nighttime sparkle.
