Several Small Issues with 2000 Malibu LS

If anyone could help in these issues I would be greatly appreciative:

1: Front passengers side window does not go down but switch works for all other windows. It does not appear to be the motor. Is there anywhere else to get a replacement switch. I got a price from the dealer that was $85.00.

2: The lights for my radio presets don't work anymore. What is the part that I need to replace it. The local autoparts store doesn't have it in its records.

3: The air conditioner (& heat) only works on levels 3,4,5. Levels 1 & 2 don't work at all. A very slight amount of air comes out when driving but when car is idle, there is no air movement. Any suggestions??

1. replace switch first, try a junk yard it should be way cheaper

2. Same thing with my 2000 Malibu, Chevy told me there is no way to
replace the bulbs and have to replace the radio.

3. Very common problem with a $20 fix (had to replace mine for the same
problem). Blower Resistor is bad, see the post before yours for exact
info.
