What causes the intermittent springing open of my tailgate

This answer was rated:

What causes the intermittent springing open of my tailgate window? It can go weeks without a problem and then springs persistently until I lock the doors very quickly. Is it the microswitch failing?
what has been checked so far?
Customer: replied 2 years ago.

Nothing!

I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked.

the cause is most likely the switch failing, as you suspected.

it could also be a problem with the lock/release mechanism itself, but more likely the switch.

Please let me know if you have further questions. Please do not forget to click a positive rating as this is the only way I receive credit for my answer, thank you. Best wishes with your vehicle.

Thanks for download. Where can I obtain special tool 009 323?

Once removed how will I know the whether the microswitch is faulty?

that is a bmw dealer special tool

you can see if you can find one online or look for something similar from another manufacturer

the switch is just a switch, it needs to be tested for closing a circuit
