    Does anyone know where the power lock relay is on a 2000 yukon denali? It is not the same as a 1999 or 2000 suburban, apparently in 2000 the denali was the only suv that gm put a BCM in. My neighbor's locks stopped working. The BCM is clicking when I press the button, the switch is good. I would like to checkout the relay but can not find it. I have found diagrams saying that it was behind the glove box. I have exhausted my google abilities. The one I found was for the blower fan. Maybe time for some magic from @99'HEARTBEAT???

    If we could suggest that the BCM used in the 2000 Denali might have been a prototype for the future BCMs, maybe we could look at the 2002 Envoy (I have a Chilton's).

    In the Envoy/Trailblazer power locks, there are two relays (lock and unlock),
    - both are operated by the BCM,
    - both are mounted on the interior fuse block.
    - no relays are on the BCM,
    - the rear (interior) fuse panel and the BCM are on the same circuit board.

    Perhaps the clicking, you hear, is the relay you are looking for?

    I will have to pull open the center console and check out the bcm again. It just looks like a aluminum box. I feel it clicking when the button is pressed. Thanks, I will keep you posted.
