How do I get my tailgate to release so it will come down. on 2001 GMC Sierra 1500

When I pull the handle to release the tailgate it will not release for some reason, It sounds like it is releasing but it seems to be stuck.

sounds like the retainer clips that hold release rods have broken, go to a body shop and see if they can open for you.then have them ck the release rods

remove tailgate handle to see if rods hooked up then can pull both rods and the tailgate should open
i would try to spray the lathces at the side and under the handle itnto the tailgate with a pentrating oil and work the handle while try to pull on the tail gate.
