Check the passing relay under the dash. It's just to the left of the glove compartment. I had a similar issue with mine when I swapped out the dash. Turned out to be that relay was still attached to the old dash and I had the hardest time figuring out what that d@#$% blue plug went to! LOL. If it's not plugged in or loose, the lights will pop up, and turn on and off, but will not go down.
