GM has had issues with fuel level sensors (in the tank) and instrument clusters. Are the rest of your gauges working correctly? If so then you will need to install a level sensor. Good Luck

try changing the door jam switches,one or all of them lost their ground.When the doors are closed the switches ground and the lights go out.If they are on a timer device the timer may be defective.

Problem with blower motor is the blower motor resistor. They are usually located next to the blower motor, a couple of screws and a couple of plugs and your done. Autozone sells them for around $30 each. Wipers you may want to check for relays under the hood in the fuse block. There may be 2 relays 1 for low and 1 for high. I have switched relays from other working accesories and got wipers to work. Sometimes bad connection.

you bcm (body control module is bad) to have the dealer replace it will run you about $400. a quick fix for the reverse light is to splice 2 wires into the wire for the center plug in your trailer wiring. now run a wire up to each reverse light, cut the green wire to each reverse light and **** conect them up. this is a seperate revers feed than the one from the bcm. the dome lights remove the light cover on the second set of interior lights (the one between the drivers seats). the two side bulbs are map lights the center bulb is for the dome lights. run a jumper wire from the right or leftside socket to the center socket. you dome lights will now turn on with just the use of that switch i replaced the back bulbs with led's soo there is no extra amp's being drawn. you could bypass the bcm but i could not find any wiring diagrams for it and i dont know if it can take the added amp's

If the whine changes with engine speed in park it could be the idler pulley again or the alternator or waterpump or the a/c compressor you can use a stethoscope or a long narrow screwdriver (2') and put it against a non rotating part and put your ear against the other end and where the noise is the loudest should be the suspect part. Be careful of the fan and belt when doing this.
