Car was fine. Now car is not fine.
Yesterday I took my car out(04, mn6, bolton mods, only 7500 miles) for a quick spin without issue. Afterwards I decided to wash it. After a typical washing of the exterior I went to start the car and things went haywire. The car will crank and fire for half a second and immediately die. The power windows don't work, the power locks and mirrors do not work, the radio does not work, basically none of the power accessories. The DIC is currently flashing reduced engine power, low fuel, shocks inoperable(magnetic selective ride), service vehicle soon. When I access the onboard diagnostics it only says "no comm." after every subheading. I also hooked up a handheld obd2 scanner and it just flat out wouldn't read. So I took the wheel well cover off of the passenger front to inspect the computer(PCM) and it wasn't soaked in there, but there was a little water. I didn't do anything different washing my car, just a routine exterior wash. Call me crazy, but I think my computer is fried. If that's the case what is my next best move. Sorry about the length of this post.
PS. - Car is currently safe in my garage. I was able to push it in from the driveway.

 

Check the wiring connectors that run in the accordion between the doors and the body. If that doesn't fix it, check the ground points as mentioned in one of the stickys.

 

Is the carpet on the passenger side floor wet?

 

sounds like you wet the fuse box area in the passenger side floor board.

I'd check your battery connections and voltage.

 

This is the THIRD of a same type problem that I seen like this this weekend.

Your serial buss is shorted. Try this and see if it fixes the issue:

Turn the ignition on and see if the problem still exist. Then open both doors and grab the rubber accordion tube between the doors and shake the hell out of it. Clear all the codes and see if any cone back

If that solves the issue, let me know and I will help you fix it permanently.

I'll try that and cross my fingers.

from his general post:
"First off I'd like to thank everyone for their responses. I checked everything that was suggested. The car is 100% back to normal(hopefully it stays that way). The harness that plugs into the bottom of the pcm was damp and the little rubber seal that is supposed to protect it was krinkled. After unhooking everything and blow drying it out the car returned to perfect working order. The only thing I can figure is the side cove cover is a little loose and water was getting in behind it and enough finally got in to cause a problem. I can't find any other cause. Happy for now though. If this problem rears it's ugly head again I know where to turn as always."

 

Soooooo glad to hear everything worked out. These guys on this forum are great.
Hope you didn't loose your religion over the weekend
