Hi I have a s500 and I've been having a problem where the car doesn't start and it drains the battery. The problem started when my father was messing with the car's fuses and relay's and tried to switch them out because the Air suspension wasn't working. One day I was trying to set the car to neutral(I wasn't able to set it in neutral) because I was trying to get a tow and when I turned the key to the on position the alarm went off and all the windows rolled down and I haven't been able to put them back up since. I just wanted to see if anyone has an idea on what can possibly be wrong with the car and if anyone knows a trick so I'm able to set it on neutral and move the car.
Thanks!

 

Hello Peter and welcome to the forum! Before spending any money on the car, I would suggest pulling the codes; so should give you a good idea as to where the issue is coming from and will make it easier to resolve.
