whynotthinkwhynot That's not going to clean off with electrical parts cleaner. You need scotchbrite pads or a new module. FYI: grease on the terminals will prevent future corrosion. A large container of dielectric grease is not as expensive as purchasing it in small quantities.

sleepyboy Holy cow that's some corrosion!

At this point I would start checking all the grounds everywhere, especially after seeing the BCM. The car was never in a flood was it? You may also want to try swapping out the headlight switch. I had to do that after having a similar problem like yours. This was after I replaced the Hazard switch a few times through the years. It's been years since I had a problem with the lights now.

I tried cleaning the corrosion, and still nothing. I'm beat.

sleepyboy Try to post a pic if you can.

bazelightyear So after pulling and untaping the entire rear harness, I found nothing out of the ordinary. I did however pull the bcm, and what I found was some SERIOUS corrosion on all of the connectors. I would post a picture of just how bad it is, but I'm posting from my phone and can't figure it out... So anyways, I'm about to head to Walmart to pick up some electrical parts cleaner, and I'm reeaally hoping it'll do the trick.

whynotthinkwhynot Here is one way to do it.

How To: Hatch wiring repair
01-26-2013 07:22 PM
sleepyboy Check the wires coming out of the body and into the hatch, those are known to get split from opening and closing the hatch and grounding out causing all sorts of weird problems. You'll have to pull the black boot back to see.

bazelightyear So I replaced the hazard switch and even the turn signal stalk, and still nothing. I'm completely stumped. Fuses are good, wires are good, connections are good, grounds are good... Is there any possibility that there's an issue with the bcm?
01-24-2013 01:42 PM
bazelightyear Thanks a lot for the help guys. I checked the connection and it's fine. I'm gonna try to pick up a new switch today and I'll let you know if that does the trick.

TerryB You can check to see if the switch is still plugged in tight. Remove one of the two center dash a/c vents and you can reach inside and push the connector on the back of the switch. This is a pic with the center console removed. This is not needed just to check the connection.
