dome light update (c900)

Jan 04, 2005 9 Replies

A bit more info on my dome light problem (see also my original thread, "dome light poltergeist"):



The light now stays on constantly when the switch is in position 1, however, it goes off when the switch is in position 0. Essentially, position 1 is now behaving as position 2 usually does. Any ideas on this?



Thanks,



John


Hey John, might be one of the door-switches that is broken, or a loose wire touching the chassis somewhere.

Good luck, Richard.

I had a problem with the dome light delay relay. There was a bad transistor in the relay assembly. The interior lights acted like there was a door open all the time. This drove the lock system and the alarm system crazy. I had to replace the faulty transistor in the relay, it was shorted. The fix was a piece of cake. I used a junk 2n2222 xistor from some dead dammit in the parts donor pile. The fix has been working fine for almost 2 years now.

good for you, but the American audience probably has no idea what you just said nor any idea how to diagnose it...

Was perfectly clear to me... but I'd go with suspecting the door switch first, and wiring to same next. The switch is right there (below?) the upper hinge, little plunger-type thing. Easiest and most likely suspect.

I had a similar problem with our '87 900 after we bought it, turned out to be the switch (in the center console). I took the switch out, took it apart and it was all corroded inside (maybe because of water leaking in through the roof left open (happened to me too). I scraped it clean, sprayed some WD40 into it, put it together again and the light was OK.

As the OP, and in addition an American, I am pleased to say that I had no trouble understanding your post :)

Actually, It was straight to the point, but it was a bad day. Sorry for the sarcastic post.
