should i just buy an icu?

Since i've owned my car, the dome light/courtesy lights/chime only work occasionally. Usually when it's rainy, or very humid. The dome light works if i turn it on, but none of these other things ever seem to work on any consistant basis. Everything else works fine; my windows, other lights, locks, defroster, etc. So would the ICU be suspect? Should i buy a new one, or is there something i can resolder in there, like i did with the main relay?

does ur door pins work? like do u see the indicator on the dash turn on and off when u open and close the door?

Mine acts slutty all the time and I eat ICUs like mad. Unless I am just getting a handful of bad ones.

I'm not sure let me check real quick. I cleaned all of them and tested them with a multimeter and they seem to be fine, just not working correctly pretty much ever. But it's odd, i figured if it was going to go bad that the defroster or some of the other stuff that runs through it would stop working too but they havent.

EDIT: hmm the rear passenger one works but no other. I'll have to find out what pin the wires go to in the icu and test them individually, or just short the terminal on something. I cleaned those switches but maybe they're beyond saving.

SUPER EDIT: Ok, so if you ever rhetorically ask yourself, "three switches cant go bad at once, can they?" then it means that you will be proven wrong. I just swapped that rear one to the drivers door and it works so i'm gonna clean them all

MEGA EDIT: I just discovered that the leading pad on the contact seems to wear faster than the trailing one, so i popped the little metal piece out that sits inside the slide and turned it the other way and in addition to scraping the contacts off with a flathead seems to have it working perfectly.

so does ur dome light turn on and off accordingly to ur doors?

Yup. My moms CR-V had the same problem. I just loaded the door switch up with bulb grease. You can look in the categories here. I looked but couldn't find them.

if you're good at soldering, you can build up the worn contact that way sometimes. i've done it on window switches and bought a few more months-years on them
