Hello
Have you checked to see if the fuse is blown?

Quoting online without seeing the damage is impossible to do with any accuracy. Visiting a trusted and peputable paint and body shop in the local area is your best bet.

I don't have the pics.
To correct the wiper arms back to their original rest position, make sure the wiper arms are in their off state.
Pop the plastic cap out of the wiper shaft, use a 15 mm open wrench to remove the nut. Pry the wiper arms out of their spline shaft and re-position them down to the bottom of the windshield.

No, this is not the case at all. The wiper parking issue that happens on the Montana / Venture / Silhouette is caused by a faulty Wiper Motor Crank Arm Assembly. Replace it. ACDelco 12494825 Windshield Wiper Motor Crank Arm Assembly, no other brands are available. Probability here is 100%.

Unplug the blower motor, install a new fuse and if the new fuse now does not blow, then your cause is a bad blower motor. If the fuse still blows even with blower motor unplugged then your cause is a shorted blower motor resistor or a burned and shorted out connector or both.

Please clarify what you mean exactly, because saying your key is not working is not specific enough. Are you saying that the key sometimes does not turn (as though it is the wrong key) or do you mean the key turns but the engine does not start? I am taking what you said to mean that the key does not rotate at all sometimes. If this is the case then the fix would be to replace the ignition lock cylinder. Even though you made a new key, the problem is with the tumblers inside the lock cylinders itself. The new cylinder would have to be coded to match the old cylinder before you install it and then a simple programming procedure has to be done before the vehicle will recognize the new cylinder. If you will attempt to do this yourself with a repair manual next to you, let me know and I can provide the add'l details you will need to do so you can do this job without outside help from a mechanic. This job is not a simple slam dunk DIY type job and requires you follow a very specific procedure or when you finish the car will still not run and if you code the cylinder wrong the key will still not turn.

Step 1: Raise the car and safely support its weight on a floor jack
Step 2: Use penetrating lubricants such as PB Blaster or WD-40 around the bolts, and tapping the flanges with a hammer (or wrench) to let the lubricant penetrate through the rust.
Step 4: Raise the muffler from its mounting posting by pulling it free of the hangers with your hands.
Step 5: Unbolt the muffler and lower it with the floor jack. Remove the gaskets that seal the two sections of exhaust.
Step 6: Use some automotive cleaner to clean the forward mating surfaces of the exhaust to prepare them for re-installation.
Step 7: Balancing the new muffler on the floor jack, raise it until you can easily fasten it to the forward sections of the exhaust system and attach it with the new nuts and bolts provided. Hang the new muffler from the body of the vehicle with new exhaust hangers. Slide the new hangers over the mounting brackets on the muffler and the car body, lowering the floor jack until the muffler is at its proper height. Then retighten the bolts that were loosened before, leaving the new muffler firmly mounted onto your vehicle, and remove the floor jack.
