02 C230 electrical nightmare
 

What's up people. This will be my first post looking for help on here, but certainly not the first time I have used some expertise from you all. Let me start by giving you some background on the situation and the car. About two months ago I was attempting to lock the car and the remote had become completely unresponsive. I was able to use the hard key to unlock and get in it, however the lock button on the dash was not working either. This issue continued for about 5 minutes and began barely working. I let her sit for a hour or so then things were back to normal. Now nothing happened with her until about a week or two ago. I was cruising at about 60 mph when all of a sudden my high beam indicator began flashing, not the lights themselves, just the indicator on the instrument panel. This lasted for only a minute or so and as before went away.....for the time being.
Now onto the ****show. Last Saturday I let my gf use my car, now it had been raining buckets that day and the day before. I get a phone call an hour into her using the car and she said that everything stopped working. I had her bring it back to me so I could see it myself since it was driving absolutely fine. When she got back to me I almost fell out.
So my windows didn't work, my door locks didn't work, turn signals didn't work, A/C was cutting on and off, radio was cutting on and off, high beam indicator was flashing, brake light was flashing, a faulty display error on the instrument panel, and substitute tail lights were on. After turning the car on and off about three times everything went away. I decided to let the car stayed parked overnight. The next evening I took her out to she how she would perform and things were fine until the next morning when just after taking off all the same **** popped up except this time the light for my battery/alternator popped up. Again I restarted, this time only once, and after about a minute or so everything was fine for about 30 miles again. When it crapped again the battery light did not come back. Now this ****storm of errors has disappeared again and has not come back. It hasn't been that long so I'm expecting it to come back but who knows when
