One of my rear power door locks is stuck in locked position. Is this a
common problem, and is there an easy cure? I gave the latch a good shot
of silicone when it (briefly) opened TOD, but it's stuck again.

For that matter, is there an easy cure for a sluggish power window?
Driver side, natch. Slower in cold weather, so I suspect a lubrication
problem.

Are there online guides to assembly & disassembly of door hardware?

Thanks in advance,
Pete Tillman, who'd wondered how long this fancy power door stuff would
keep working.

Answer: about 8.5 years (truck built 8-96).
