weird keyless entry problem, please help!!

[gabelivingston]

I have a 2001 GMC Sierra. I know my remote and receiver are working because I transferred both to another vehicle and programmed and it worked. On my vehicle, it will go into program mode but no matter how long I hold down the unlock/lock buttons it will never lock then unlock the doors. The only fuse I can find is the one under the hood, and it is good. I'm getting 12V to both orange wires and the ground is good to the black wire at the receiver. Any ideas would be appreciated, or if any one has the wiring diagram for the keyless system.

Thanks,
Gabe Livingston

On the old body style trucks, the cig ltr fuse provided power for either the power locks or the rke receiver
