Window up and down rapidly; beep beep; headlight switch won't turn

[marilynmichael]

2002 Targa

Has been a bit humid inside the car, but not wet.

Now, when I close the driver's door, the side window, opens slightly and then closes back--and repeats. A lot. I open the door and sometimes this stops the behavoir and sometime is does not. Repeat until it stops.

When I go to lock the car, I get a horn beep--which as I understand means something is not closed properly. I open and close the doors and then it goes away--but I swear, the doors are closed properly

Today---pouring rain. I go to turn on the headlights--turn the knob. Will only physically turn to the parking lights--not all the way to the right for the full headlights. I pulled out the switch to put on the fog lights and they came on fine. I tried to turn it to full lights while pulled out, but it wouldn't budge.

Something appears to be funky with the electrics.

Clues?

Thanks for you help!

Whenever I see the words "random" and "electrical" I go right for the battery and chassis grounds.

I hooked up the battery and charged it with a trickle charger. Charged to full over night. Shows 14 volts on the gauge. Guess that's about right.

Problem still exists.

I noted that my seat belt, when fully extended, seems to be a bit damp--both of them. Maybe they are just cold -- but they kind of feel damp, so I thought--ok, let's check the drains. Front ones near the battery were fine. Nothing clogging. Cleaned it out a bit and blew compressed air down. Pour water through them and water came out below fine.

Checked the front drains of the car with the Targa roof retracted. They were clear as well. Blew air and poured water through.

I could not see the entrances (holes) to the rear drains, so I semi-gave up, hoping the problem would go away.

Alas, and not surprising, the problem still exists.

The interior lock button sometimes 'works' and sometimes does not. The car 'beeps' when locking sometimes and sometimes not. The driver's seat moves forward and back sometimes and sometimes does not respond to the switch.

Today, was warm and sunny so I went out on the hunt for the rear drain 'entries'. I could not find them. I did find the kind of pop in, pop out funnels from the targa roof to the side roof drains. They were properly placed.

While doing that, I noted that the 'mesh' along the driver's side of the rear roof (rear roof opened on the Targa) was very damp. The passenger side was not. This semi-confirmed in my head that the 'rear roof drain' on the driver's side must be clogged.

I poured some water from into the open sliding roof. Water came out behind the rear wheel. But, maybe it drains slowly--dunno.

So--I pulled the rear wheel based on what I had read on some posts to see if the exit point might be somewhat clogged. I pulled the plastic covering from the wheel well hoping to see the exit point-but nothing there. I poured water again from the open roof and noted water exiting kind of from the rear portion of the wheel well--but not from some clear exit point but kind of from a metal seem.

I cannot find the entry hole for the rear roof drain and I cannot find the exit hole for the rear roof drain. I've looked thought the diagrams, etc and I cannot find it.

At this point, i'm about to take the poor thing into Porsche and throw my hands and wallet in the air. I'm afraid the electronics are a bit compromised (I checked under the seats and I didn't really find it damp and certainly not damp--but the car was covered (Porsche cover) and out in some heavy rain for two weeks a while back) by moisture/condensation. And--the 'mesh' on the left of the rear roof was defintely damp/wet but I cannot find where the drains are.

To the shop or another idea?

Thanks for your help

For most of your problems it sounds like the switch inside the door latch is going bad. Not sure about the headlight issue.
