1. Lift the tailgate handle and look between the back of the bed and the tailgate (on the inside) to see if you can see the latch being released. If they are not you can stick a small flathead screwdriver in there to get it open and go from there. One of the arms probably came disconnected?

2. Go to autozone or whatever and get a spray can thingy of throttle body cleaner. Pull the plastic piece off the front of the throttle body and spray away. I usually park on a hill with the front of the truck facing downhill so all of that gunk doesn't flow back to the intake. Spray the crap out of it and use a rag or paper towell to clean the stuff off. You're not going to get it all this way, but you should be able to get it clean enough for the pedal to stop sticking. You can remove it by removing the 4 screws that hold it down, but I don't know if you need to replace any gaskets or anything, so I haven't done it to mine yet.

3. You mean your A/C condensor, right? Go to a junkyard, get a new one, swap it out, go to wally world or wherever and get the R whatever it is stuff for A/C and refill it. Flush the system??? That sounds like BS. When something in the A/C springs a leak all of the gas escapes. What's left to flush??? Maybe they meant to refill the system?

I'm no expert, but I hope that gives you some ideas.

They're great trucks, mine has 90K and no problems at all yet, just routine maintenance. I do use fuel injector cleaner in my tank at least once a month and I clean the throttle body about once a year.
