i just bought a 97 civic sedan a few weeks ago and it has power locks but the power lock switch doesn't do anything. there is only one and its on the driver's door. do you think the switch went bad? anything i should test to see? where should i get a new switch from? thanks.

 

Is 20A hood fuse 51 blown?

 

replaced the switch and still nothing. i checked the fuses and they are good. i took off the door panel and noticed there is a power lock control in there. i have power going into the control box but no power going to the switch. do you think it is the power lock control box?

 

 

can i do these tests with a test light?

 

You can only easily do the voltage tests with the test light. You need a multimeter for the continuity tests. Note that some tests require neither, just a jumper wire.
