Electrical problem
2005 Chevy Equinox All Wheel Drive Automatic 90000 miles

PLEASE HELP. My sunroof was open for a few minutes during rain. 3 days later my instrument panel went crazy. All warning lights came on but needles were all at 0. Radio and power steering worked on and off. Next day radio locked as well as power steering. Now radio has nothing on screen at all and speakers dont work (no chime or anythging thru them). I checked all relays, fuses, battery all fine. After 1 week I decided to check connection to radio and power steering. Now car wont start at all. First when key turned it ticked then 1 click and nothing. Almost like my battery is dying. Seems like anti theft issue interferring. Strange cuz now that my car wont start I can hear noise in speakers when turned key

This is a tough one as if I was fixing it I would need to scan it to see what is going on. Possibly water got into the body control module, I would disconnect the BCM, it is located in the centre console built into the fuse block. Disconnect and reconnect after 20 seconds. Try also a global disconnect which is take both batter cables off and hold them together for 30 seconds and then reattach. This provides a reset of the vehicles communication system. Aside from that I guess you would need to have it scanned.

Thank you. That is what ive done and now most of my car is fixed. I found the culprit is the amplifier under the back seat. All speaker wireswere corroded. And the actual circuit board looks like its been damaged over a course of time. When I plug my onstar/interior light fuse in all my warning lights come on so I still have a short.

This probably will not pertain to your short but since you have noted that your amp is corroded, does your car have a musty smell? I would urge you to check the spare tire well for water. Equinoxes for that year until 2008 had water leaks. The rear hatch weatherstrip can leak underneath so you would have to remove it, fill the channel with weatherstrip adhesive and reinstall. Also check the body seams around the taillamps after removing them. An old trick if the well is filled with water to to drill a small hole in the rubber plug at the back of the spare tire well to prevent any possible water from getting in and being held there.
