I have just bought a 2004 BMW X5. At the time of the inspection, everything was working just fine then the owner removed the "boomerang" which is supposed to be a satellite tracking system.

When I received the car, trunk does not open (not from the key or the button or the button inside the car). It always makes a clicking sound coming from the trunk at specific intervals even with the car off and locked.

Whenever I click the trunk button, a small sound from under the glove compartment comes out but nothing happens at the trunk. And I just found out that the rear wiper does not work aswell.

Any pointers or ideas? Thanks!
