2 Alternator/generator/regulator problem of the 2001 BMW 330

Failure Date: 01/20/2015

I've replaed the window regulators in my car several times due to the material being cheap. The gears wear out and/or break apart. Each time it's between $150 and $300 to repair. The window stops half-way down and can't be moved. This presents issues with safety during inclement weather and makes it very easy to get into the car to take valuables and potentially steal the vehicle.

3 Alternator/generator/regulator problem of the 2002 BMW 330

Failure Date: 03/01/2013

The battery of the car drains out every morning and I need to jump start my car everyday in the morning. I have got the battery, alternator and the charging circuit checked and there are no faults with those. The battery is only an year old. I suspect that something is running in the background after engine stop or there may have been a short circuit which is draining out the battery.
