#182 of 409 Comfort Control Module Blues? by sadvw

Feb 01, 2008 (6:31 pm)

Hello All,
I have been reading posts, and trying not to be redundant in my own post, but... I think I may have CCM problem but not sure, have tried to diagnose/fix but now I'm stuck: 2000 VW Passat, 71K, automatic trasmission
 
History: Big rain storms 1 week ago. Found 1/4 inch standing water drivers side (you see where this is going). Wet corner near drivers side of sunroof, and flooded sun roof gutters, suggested that water leaked in through sunroof and came down column near rear view mirror and onto floor. Car seemed otherwise fine. Has worked fine for a week, including being driven long and short distances, and multiple errands (on/off/on/off with electrical, engine, etc).
 
Symptoms: Last night left work, remote key did not work to open car. Opened with key manually. Found that the following did not work: dome lights, trunk release, sun roof, windows, unless they were lowered/raised by using the key in the door, and car would not turn on. The headlights and radio did work. Needless to say jump start did not work. Had car towed home, as was 9pm and did not have mechanic to drop it off at (long story). Found that key batteries dead too (tested w/ volt meter); replaced batteries in case alarm was preventing car from working, didn't help, but needed to be done anyway.
 
Plan: Mechanic friend came last night and tested battery and all fuses, all checked out normal. Not much else he could do at midnight and not in his shop. Today, after talking to 3 mechanics, determined that CCM most likely problem. Pulled up carpet, located CCM, removed. Condensation found around cable bundles/under carpet and insulation, which are still very damp. No condensation inside box, opened CCM, no evidence of moisture in there. Put heater in car to dry, left CCM open (but covered to avoid dust collection) for several hours. Carpet dry on top, still damp underneath of course. Plugged CCM back in, checked all plugs near where those cable bundles go into car on left, below fuses, to make sure dry and not loose.
 
Status: ARRGGH! Still won't work! My CCM did not seem wet. Is it possible it's done for anyway? Or is the problem most likely elsewhere? Any ideas for my next steps?
 
THANK YOU!!!!!!!!!!!!!

I've been going through the same problems as you. Although it doesn't appear that my sunroof was the issue. After I got the wiring harness good and dry (like 2 days dry) my problem seemed to resolve. This site http://www.headfuzz.co.uk/?q=vw_ccm , if you haven't seen it already, shows a good example of the CCM problem. You might want to inspect the wiring harness pretty well to make sure that the wires haven't corroded through. There is also a computer on the passenger floorboard. I forget what that one controls though. My Passat had water throughout the entire car. So you might want to look into pulling up the carpet on the passenger side and in the rear seats also. Good Luck...I feel your pain!

#185 of 409 '98 Passat by jrim

I recently bought a '98 Passat. I noticed the rear defrost and cruise control was not working. I checked the fuses and sure enough there were not any in those particular spots. I replaced the one for rear defrost and now it works fine, however I noticed there is no wiring coming into the one labeled cruise control. I was wondering is there an easy way to take the wiring from another fuse of the same amps and hook it into that one? Or does it sound like there's another problem w/ the cc all together?

I am having similar problems with my 2002 Passat. The car has been "flooded" twice in the past two years. Dealer didn't do much about it, and I didn't have any electrical problems until this week. Problems include power locks aren't working, car won't start until after I turn the key on and off a few times. I use the key in the outside driver's side lock to supposedly lock the entire car only to find it completely unlocked when I arrive at my car after work today.
Any chance I can "fix" the problem myself (or my husband, who is mechanically inclined)?
Thanks.

Maybe. You'll need to pul up the driver's side front carpet to acces the Comfort Control Module that resides in a well under the driver's feet (LHD). Clean up the water, drain the well, dry the module completely along with the carpets. Put it all back together and see what happens.

I have a 2001 passat gls,,,the keys didn't work to turn motor, or the power windows, sun roof and remote door locks don't work either. Took it to dealer found out wet ccm, went to junkyard found matching one in excellent condition, plugged it in everything works except power windows and remote door locks,,, you can hear a clicking noise in any window that you attempt to open , but thats it, just a clicking noise in the circuit board in each power window module. any ideas or suggestions,,,,,,,boy what a crappy design flaw by VW

I am amazed. I have been unable to find a Passat in a junkyard anywhere. Can you tell me where this gold mine is? I need some parts for a 2000.
