‘87 Chevy Astro, Door Lock Relay

Q: 
I own an ‘87 Chevy Astro V6. It had a problem with power door locks. I am sure I need to replace a door lock relay but I don't know where it is located. I checked the fuse box but it is not there. I guess it’s somewhere in the engine area or inside the door. Can you tell me?...Kevin

A: The ALLDATA Information System shows the door lock relay to be mounted under the right side of the instrument panel. Also note that the door lock module (yes, some sort of computer had to be mixed into your door locks) is located adjacent to the door lock relay. You should also note that there are 2 circuit protections for the power door locks. One is the Accessory Circuit Breaker at the fuse panel and the other is a fusible link which is located in the engine compartment. Both of these components must be good before there is any chance of getting the power door locks to operate.
