Flasher and Rear Windows don't open

[bmwikonline]

I bought 318i few months ago. It has few problems with it.

1) Flasher or Hazard lights don't work.
2) Rear windows don't come down.
3) Alpine security systems is acting wierd.

When car is armed and I put my master key in door alarm goes off. I don't know maybe thats how it is supposed to work. The security system has motion sensers if we come close to car all four lights will blink. Are these different bulbs than the flasher lights?

My wife was able to lower the rear windows after kept on pushing the button for 10 minutes. The last owner has replaced the engine. I don't know what's going on or all these are related. Fuses seems to look ok.

Thanks in advance

1. if they blink for the security then your bulbs and fuses should be fine. I would check the switches and relays.

2. Could be a blown fuse, bad regulator, bad switch, broken control arm, worn motor, or combination of any.

3. If the alarm goes off when the car is armed and you inset the key then it is functioning correctly. It is sensing the motion and vibration on/in the door and activates.

Thank for your reply, Is there any way I could test the swtich and relay.

My 325 did the same thing. The switches were not connected properly under the console.... just pop up the console and fidget with them and they should start working.

you should invest in a voltmeter. You can then test the wires and see where its not getting power.
