Title says it all, I haven't had a whole lot of time to check this out, but I figured I would ask you guys before I start chasing ghosts.

So basically, I start the car, sometimes all 3 of these things work flawlessly, other times I start the car, all 3 things don't work at all. I would assume this is a ground issue. Seeing as how I can't really think of anything else that would be common (see what I did there?) lol. between the 3 devices.


Thanks in advance, you guys never steer me wrong.

Most likely your ignition switch. When it goes out next time turn the switch back a little and see if things start working. Thats what mine did and I heard it was a common issue.

The accessories you listed run off of the IG2 fuses which receives power from the Black/Red wire of the Front Harness that mates w/the Ignition Switch. So, the Ignition Switch pigtail connects to the Front Harness through a series of plugs. One of these plugs has two wires, one B/R and the other Blue. W/key to on the B/R wire should have battery voltage to it. If it does then it powers a series of fuses that are part of the IG2 bank. The Wiper fuse powers the logicon too besides the wipers themselves. The sunroof is powered by the Sunroof fuse. Both of these fuses are IG2 fuses so both of them are powered by the B/R wire from the Ignition Switch w/key to on.

cool, thanks for the answers. I will check out my ignition switch. Any quick and dirty way to just clean it up? Or am I looking at getting a replacement to fix this issue?

its a "wear" part, as in it wears out. not really something you can "fix" if that ends up being the issue just replace it.

In case you didn't know, the ignition "switch" is completely independent of the key cylinder, so replacing the switch doesn't affect the key at all.
As for repairing the switch, trust me, you DO NOT want to open that little sucker up, it is fiendishly complicated.

I also have this problem. Doesn't happen very often, but it sure is annoying when it does happen! (especially if it starts raining)

Guess I'll have to add new ignition switch to the to do list!

If it happens to all of these systems, and happens more often when raining, I would suspect it is more likely to be the ground that is corroded or broken. All of these systems ground in the same place. If you pop the hood and look directly underneath the coils that are behind your driver's side wheel well, you will see the connector that plugs directly into the wheel well itself. That is your ground.

Remove the coils so you can get at it, then unplug it and check the condition of the wires, and connectors. Also check to make sure the bolt that holds the terminals to the wheel well isn't covered in corrosion as well. While you have all this off to inspect it, I would recommend cleaning it all up, removing the ground bolt, cleaning up the threads in the body of the car, and putting a new ground bolt in there with a bunch of dielectric grease.

When just one of these systems is failing, it is easy enough to blame it on loose solder joints on the PCBs, but when they all start failing at the same time, it is more likely the ground I mentioned.
