Cab interior lights

In the process of repairing the dash lighting I realized why my interior cab lighting didn't work. This is pretty easy to diagnose and clean up, maybe this will help someone.
  • The under dash light was blown (Pretty important to have a functioning bulb)
  • Both of the door jamb switches were rusted solid (the button wouldn't push in or out)
  • The top shell light bulbs and connectors were so rusty they weren't making a connection
  • There was a wire split in the power wire for all the interior lighting (the orange wire)
  1. Reconnect the orange wire
  2. Get new bulbs
  3. Cleaned up the top shell interior lighting connection with a dremel and wire brush
  4. Repainted the light housing
  5. Pulled the old door jamb switches
  6. Replaced with these Door Jamb Switch I've not received these yet but will update once I install them


Blown light bulb under dash.


Door Jamb Switch rusted out. Both doors were like this. The switch just screws into the door jamb. One major warning, do not pull the wire out through the top. It's a major pain in the ass to get fished back through. It took several minutes and a lot of prayer.

Taping up.


Nice and silver

Re: Cab interior lights

I didn't know those switches threaded into the jambs. When you say you pulled the wire out the top, you mean the dome light?

No, I'm refering to the under dash light that's driven by the Orange power line and the white ground line. The white lines are the lines that connect to the door jamb switch.

My under dash light is located just to the left side of the glove box barely under the dash.

The white wire that connects to the door jamb switch enters the door jamb from the interior about 6-8 inches above where you see the actual door jamb switch.

On the drivers side it's just behind the dash behind the A/C vent.
On the passenger side it's just behind the dash beaneath that A/C vent.

Re: Cab interior lights

Replaced the door jamb switch with these guys from Rockauto. I think they were about $1.00 a piece. They fit well, and screw in nicely but there's a little wiggle in them. I would have preferred a more firm screw down. I'm going to add a washer to see if that helps.

Also on a side note, there is enough thread for you to adjust these to your door and door jamb make up. I would image all are similar but just in case, you can just barely screw it in for a long switch striker or screw it all the way down to push the striker further from the door.
