Dome Light Dilemma

Post by ARCHINSTL »

OK - what am I missing?
The DS door switch for the dome light permits only a dim lighting of the dome light (rear light OK). The switches of the other doors and the hatch permit full illumination. When the DS door is open (and light dim) and one of the other doors is opened, the light brightens.
I've removed the B-pillar trim and checked the switch as I thought it was a grounding issue; it is not corroded, etc. I've removed the wire and it lights OK.
I'm being obtuse, but - what? It's not a biggie, but it's annoying, like squeaks in the dash.

Mentioning the light - is there any other bulb that is brighter than the little stock bulb? I put new ones in a couple of years ago.

Since the light brightens when the loose wire is grounded, I thought it would be corrosion between the switch and the body for grounding. I cleaned it with no improvement. Is it possible that the problem is internal to the switch, with only some of the little electron guys getting through?
If so - anyone have a switch available?
Thanks,

Hey - just yesterday I finally adapted a sunglass cubby a member got me some time ago. A few years ago I'd installed an ancient SONY pull-out radio/deck from the later '80s (don't laugh-it is a twin to the one in my p'up. Besides - what's a CD?) and discovered yesterday that the cubby is set to fit on extensions of OE radios only. So - it took a lot of whittling and sawing the cubby and gluing and drilling new holes in the binnacle and then in the "struts" of the binnacle, but BY GOLLY, I now have a sunglass cubby that looks OE.

sounds like a marginal/high resistance contact or conection is the door switch circite. Caution on the brighter light, when I work on my car I sometimes leave the door open all day and it is a warm day, the light will damage the dome light cover from the heat (I have replaced it several times), a brighter light would damage the white translucent light cover even faster. Unless you can switch to a "cool" lite like an LED or something similar.

Funny you should mention the light melting the cover - I actually did this on a Morris many years ago. Since then, if I'm keeping doors open longer than a "few minutes," I always flip the switches on both lights.
Kinda like how I learned my lesson on leaving the ignition key turned to "On" a few years ago in Goldie; it fried the whatzit in the dizzy and I had to get a reman. And of course, when perusing the OM later, it specifically warned against leaving the key in that position...
