Help with power locks/mirrors on 2000 S10 Extreme

Hey,

I'm working on a 2000 Extreme and can't get the power locks to work. There is power going into and out of the switch but no action. Is there a relay that these two are on that's not not labeled? The fuses are good.

Also,the cd player mounting kit for a 2000 Extreme isn't different than one for a 98 S10, right? For some reason the mounting kit out a 98 is too wide for the 2000 and the screw holeds don't line up. It's the same body style and same dash style.

Thanks for the help.
