Does anyone know how to check if a relay is bad or have a link that tells how to check one. My power locks arent working and wanted to check if it might be the 19 year old relays.
Thanks

 

A simple way you can check is find another relay thats the same and plug it in and see if you can hear it click or feel it. That is a way to see if it is good. its not the best and doesnt mean it is good but will get you in the right direction. You can put a meter on to the coil prongs and check it. But reall it just s part that you just buy new. lol

 

you can do it with an ohm meter. If you don't have one, then just use another relay in its place and see if it works
