I recently fixed my central locking by installing a new (used) actuator pump. It seems to work fine UNTIL the trunk is opened. Today, It locked all my doors and locked my keys in it while it was running. I was not impressed. Sometimes, it stops working and makes a clicking sound until I unplug the cables and plug them back in. Really, really annoying. Any ideas out there? Thanks.

 

check teh relays and the electrical connections if there are any at the locks and also see if all the vacum hoses are hooked up propperly
