If the 2005 Montana is similar to the 2001 Montana, I have a solution. First you'll need a hexagonal wrench (the 6-sided L-shaped wrench). The tail light assembly is held on by two screws. You'll need the hexagonal wrench to remove them, because a normal screwdriver won't do it. I also had to use a conventional adjustable wrench to get the leverage to turn the hexagonal wrench, because the screws were in there pretty tight. Once you remove the two screws, the whole tail light assembly should come off. Mine required a little force and I had to play with it a bit, but it came off without a lot of work. There will be one set of wires that connects the tail light assembly to the rest of the minivan--try not to damage that set of wires. Once you get the tail light assembly off, you'll have to take apart the assembly that actually holds the lights. No tools should be required. It's held on by four plastic catches. Just undo the catches (easier said than done, but still not too tough) and it comes apart. Then you can pop out the old light and pop in the new light. Then re-assemble. For me, it went back together much easier than it came apart.

For the sliding doors you need to clean the contacts, there are 6 or 8 on both sides, just wipe them clean as they are probably covered in oil/grease/grime.

I have a 2006 SV6 with the power sliding doors. The problem that I found was with the contacts on the door ( They are called plungers) the movable pins were losing connection with the fixed part The plunger is very easy to replace if you can find one. The plungers are covered with a rubber cover and is held in place with 2 plastic pins. My Pontiac dealer could not even find one in his books or even a picture of one, and claimed that he had never had anyone come with a door problem. My Chevy dealer said that it came with a wiring harness that is not needed for $154. The cure that I came up with was to take the plunger block apart (it snaps together)and replace the rusted out springs then solder 3" wires to the end of the plunger pins (they solder easy) to the tabs that go to the plug(pop out the tabs or you will melt the plastic. It took about 45 min. now the doors work like new and will never loose contact again

I had a similar problem with my 2006 Montana. It ended up being the foam shield donut looking thing that stops the parking brake cable from hitting against the middle of the rear axle. Fixed it with foam plumbing insulation and electrical tape. Better than new. Hope this helps.
