Rain problems

[Ronnie38]

996 C4 my2001 cab Had very heavy rain, didn't drive the car, but left it in the driveway. Had the alarm go off three tiime overnight got up reset it .after checking out if it was a real alarm, appeared to be lighting and thunder .Next morning all the windows were open and a couple of inches of water inside. windows waouldn't go up, seats wouldn't move, so pushed it into the gargage removed the alarm cpu and in process of tying to dry it out.

what would cause the window to go down?

Ronnie, it sounds like "Hal" has taken over your CPU...  

 

As aside, I had my car on the lift and wanted to activate the alarm, it wouldn't work...  Once the car was back on the ground the alarm worked.  Pretty scary what goes on in that little black box...

 

Let us know if drying out the CPU did the trick...

I agree sounds like you have one or more plugged drains (search the site for drain locations and tips on clearing them).

If you remove and dry out the alarm control box quickly (before corrosion can set in) it can sometimes be saved - otherwise you are looking at new (expensive) control box plus time to program it.

Got the alarm CPU in rice right now, will check the drains. First I have to get the top into the service position to remove the ECU to send it with the alarm CPU to Specialized ECU repair if the rice don't work.

I tried to Manually move the top, The clam shell drive 5 mm drive was stripped, Will JB weld a 5 mm drive socket into it today. Question can I supply 12 volts to the top control line to engage the electric top control? with out damaging any thing else.

Had the same exact problem. Heavy rain overnight, came out in the morning to find the windows down, ftrunk and engine lid open and a swimming pool under the seats. Utlimately I needed to have the alarm computer replaced. It would seem if it shorts out it opens everything up.

 

After checking out the car after this incident, it was found that a drain was chewed up by a rodent and the water was draining into the car.

 

Good luck with drying things. My car was so bad soaked I even needed to replace the leather on the front seats.

The JB welding of a 5 mm hex socket didn't hold, Had foot surgery so will have to wait the car is in my A/C garage with carpets and seats out and being dried. Will try to use a easy out in the al hub to open the clam shell so I can remove to ECU and send it and the alarm CPU to ECU doctors for repair. the need the ECU and Key to reset the immobilizer. Is there a hidden cable to open the engine bay cover like the trunk lid has?

The engine bay cable is coiled under the left rear tail light. You can get to it by gently wedging a plastic spatula between the bottom of the taillight housing and the body. You should then be able to fish it out with a thin wire hook.
