Not sure quite what youre asking. Do you want to check the fuse? Is that what youre asking? How do I check a fuse. Normally you can see the wire through the middle to give a quick indication. This wont always mean the fuse is ok. The best way is to use a multimeter and measure the resistance of the fuse. It should be really low, ideally 0 ohms.

The best way to test a door lock is to locate the wiring for the door lock usually in door boot or kick panel. Use a test light with a probe and poke each wire until the door lock is activated. How ever be sure to they are not vacumm locks

You will need a Multimeter to run some test on the switch and the wiring.

Do you: Want to know how they work? Want to know how to test? Want to know how to replace? What kind of vehicle is it in? What are the symptoms? Your question is too vague.

It should have only a fuse and a switch, no relay. Check ALL of the fuses with a test light.
