Where is the locking relay located if any? My power door lock button works most of the time but sometimes it won't. Even with the remote.

Thanks!

Check DR/LCK fuse 15amp in the I/P fuse block. There's no locking relay-the BCM ( body control module ) controls the door lock system-Have it checked out

Thought so. I can hear the clicking coming from the BCM when pushing the lock button. Would you happen to know where I find the part # to the relay on the BCM. I've seen quite a few people fix this problem by re-soldering a new locking relay to the BCM saving hundreds by not replacing the whole BCM.

Thanks again!
