1999 Bravada issues
 

Hello all,

I just purchased a 1999 Oldsmobile Bravada AWD. Right now, I'm having two issues, well really three:

1) The air conditioner does not work (fully). It blows cool air, and merely needs recharged. Do any of you have any idea as to how much this would cost?

2) The electric mirrors only move down on both sides. Anyone have any idea as to how to fix this? Ballpark cost?

3) When turning very sharply, especially backing out of a driveway, the wheels thump repeatedly until their direction is reversed. Research tells me this may be the transfer case fluid. Sound right? If so, any idea on cost?

Thanks in advance for the help. It's much appreciated. It's a great car, just needs a little TLC.
