My 1994 Bravada doesn't always pop the rear glass open when I push the button on the remote or the dashboard. The solenoid does actuate but doesn't seem to be pulling hard enough the release the glass. I greased everything up, adjusted slack out of the cable out of the solenoid and cleaned up the grounding strap to the tail gate. I don't know what to look for next, and if the solenoid needs to be replaced, where can I find one?
The key does open the glass easily.
