Rain ruined my 2014 Jetta Sportwagen

[tommyesteban]

Hi, I’ve been looking all over this forum, but can’t seem to find any help and now I’m asking if anyone has experience something similar to me. After the very long rains that we had in California, my car started acting weird. The engine starts no problem, but now all my electrics are gone. For example, my turn signals are gone, my horn is gone, doors don’t unlock, truck won’t unlock, headlights always stay on when the engine is running, to name a few. I suspect that water enter in my moonroof, which I know is a common problem with Volkswagen. It got the fuse panel that is near the A pillar wet. I changes all the fuses and even put in a new battery end, it still hasn’t resolved my problem. Is there some ground in the cabin that could be rusted? This has been bothering me for some time and any help is greatly appreciated. Thank you.

google CCM comfort control module , its behind the hush panel on the drivers side and it gets soaked and corrodes up, it controls most of the functions you speak of.

@tommyesteban : You're not alone, e.g.: https://forums.tdiclub.com/index.php?threads/body-control-module-got-wet.487658/

Body Control Modules (BCMs) come in 3 varieties for our wagons: low-line, mid-line, and high-line, dependent on installed exterior lights configuration. Base model is low-line (no fogs); mid- adds front fogs; high- adds bixenon (HID) headlights. Note that Tiguan shares our BCMs, so you might look for salvaged Tiguans, too. --g

Also, seal the sunroof, it will leak water even when working perfectly. Open it up, get it nice and dry- you're in California so the rain surely won't last long- then seal that thing shut forever. I wrapped my roof in white vinyl. Also check your floors and spare wheel compartment for water, you may need to bail some water out of your car.

I will never buy another VW with a sunroof ever again! Too much trouble.

I've owned Audis with "normal" sunroofs since the '80s and never had any problems with water in the cabin due to plugged drains. The newer panoramic sunroofs, however, seem to be another story if they are not maintained (cleaned and lubricated) regularly (or rear drains were installed poorly in production). Good luck getting this resolved. --g

Regular sunroofs are fine if the drains are not neglected. The pano roof needs a bit more TLC, but the awful greenhouse effect in the heat and creaking and rattling in the cold would make me not want one, and that makes no difference whose it is. The Lexus RX330 had a [rare] optional one, and they were junk, too.

White vinyl roof wrap. No more water, no more heat dome, no more sunroof, but sunroofs are wildly overrated. Oh, vinyl also solves sunroof creaking.

All the dubs I have with sunroofs (about five currently) and all the ones I've had over the years with them (more than I can remember) work perfectly fine, and I use them quite a bit. That may be part of the issue, too, is people just don't use them. But.... as I stated, the pano roof is a very different animal.
