I'd bet your battery contacts are poor; get your front hood popped open with jumper cables per the owner's manual, and undo and reconnect the wires to the terminals on your battery and see if you're back in action.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Hey guys, my 02 cab wont start after i took it to the carwash , i got the car washed drove a block pulled over turned it off for a second and now it wont start back up. I put the key and turn and the car has power , dash lights and radio comes on but the hood or trunk wont open with the button, the car will not crank though , The alarm is also not working , i lock and unlock the door manually and the alarm does nothing. Key FOB doesnt do anything either... HELP PLEASE!

POST 2Original post

You are not suppose to put 911's through car washes, EVER! 1) disconnect the battery, 2) open the air box and see how wet the filter is 3) wait a couple hours till the engine is totally dry 4) cross your fingers and try again

I wash Baby Car everyday ~ so thanks - I guess I don't ever want to be temped but the touch less laser lazy wash ....

POST 5Original post

I'd bet your battery contacts are poor; get your front hood popped open with jumper cables per the owner's manual, and undo and reconnect the wires to the terminals on your battery and see if you're back in action. Water can get around that area if you spray water hard enough!

POST 6 / ORIGINAL POSTEROriginal post

I let my friend borrow it and he called me with the bad news! i dont know if its the battery , the car has full power, all dash lights come on and the radio works but windows wont go down, weird i will try what you guys said and will update you

POST 7Original post

If I understand you correctly then, no windows/no starter but everything else works? Dry it out thoroughly. While we're waiting for it to dry start checking fuses. And see if you can get any scan codes.

POST 9Original post

I recently had an issue with my cab, the roof drainage points were blocked and it flooded into the passenger rear foot well. Apparently there is some rather expensive modules under the seats which handle the central looking/ alarm I was told. Have you checked the carpets to see if they are dry and also when did you last get your drainage cleared. Good luck - sounds expensive whatever it is Jack

POST 10Original post

I autobell twice weekly. Autobell is an automated car wash chain in NC. Never an issue and I hope to never have an issue with my daily driver, in the rain, snow, parked outside at the airport everyday car.

I have never put any of my Porsches through a car wash (personally I like to inspect my vehicle closely as i hand wash it), sorry to disagree but the whole thing about not putting 911's (or Porsche paint) through a car was is a bit of a myth. I have friends that regularly auto wash their 911's and their cars look pretty damn good after years of doing it routinely.

POST 12Original post

I've run mine through a car wash twice, but i prefer to hand wash it. No harm done but the car wash though. I'm confused though. At first you said you were driving, then you said a friend had it. If the latter, I'm not sure you really know what happened to your car. Hope it works out, but I'd be surprised if a car wash caused the problem.

POST 13Original post

Hello everyone. First post to go with my first Porsche! Sorry to hijack this thread but I've got a 996 Cabrio 02 and I'm having exactly the same issue... Leak flooded the rear passenger seat and footwell (I took out over half a bucket of water). First symptoms were the alarm going off for no reason. The strange thing is that I took it out for a 15 min drive with the heater on full and windows down to help dry it out. I parked the car and the next day it wouldn't start. I peeled back the rear carpets and the sponge underneath them was still soaking so I've been trying to dry it out with a hair dryer for a few days. Its (carpet/sponge) almost totally dry apart from some edges but it still wont start. In the meantime I've also changed the battery as that was only showing about 10 volts. Also tried to jump start it using the terminals in the engine bay but still wont start. Any ideas would be welcome.

POST 14Original post

Start a new thread of your problem. Disconnect the battery. Pull the alarm module out from under the passenger’s seat. Open it up and dry out the inside. If it was just wet you might be able to save it. If the water has been in there too long you might have terminal & PWB corrosion.

That is in the Porsche 101 Manual! That even makes me cringe just thinking about it! jmo

POST 16Original post

Recent Panorama article said never to car wash your 996. High pressure water will overwhelm the drainage channels and you will get water into the cabin

POST 17Original post

not to mention scrape the hell out of your 10 in (or 11 in) wide rear wheels the tracks are not made for that wide of a wheel with the low profile tires So if I read this right - you friend borrowed the car and to thank you ran it through a car wash? I would look for a better friend - whenever people loan me their cars I wash them too...but I would never go to a car wash for that - I give them a loving bath...it's a sensual thing and I enjoy every second of it - why would you NOT.....I love running my hands over the curves
