The solder they use contains on lead an crystals of some type can grow an cause cluster problems , parasitic drain on the electrical system killing the battery over night , after a coulpe days .

Fuel economy is mostly driver habit dependent, this assumes you have no check engine light on or flashing and that the tires are properly inflated and the engine has been keep in a good state of tune. If there is no Check engine light the system is performing as it should and you may have to look at the way you drive.

Make sure the high beam realay under the hood fuse box is working. You can swap the hi beam relay with the horn relay to test. The hi beam filiament in the bulb can be open too.

a single click usually means the starter. multiple rapid clicks while the key is in start position usually means battery...if battery bad, could be due to alternator, but you likely would have noticed a battery light on the dash while driving before.

Well if the pump doesn't work then the air ride won't either as it is what pressurizes the system. I suggest you pull the air pump and test it to see if it runs.

Replace it

The radio fuse is located in the console fuse block located to the left of the glove box nrar the floor, the Radio fuse is number 37.

Call any major autoparts store for the correct answer. There are updated torque specs for the gm 3.4 vs in order to deal with a common issue of leaking intake manifold gaskets. They should have the correct updated spec for you vehicle based on the specific Vin number

if you heard the pump befiore ( that hum near the rear) than most likely the pump has burned out , i would have it tested and replaced if needed

I would take a look see at the ground circuits for the none working lights . The incandescent back lighting lamps are then grounded at G200, G301 and G302. You would need factory service info for the location of the grounds .Like this from buick G200 Right side of the I/P, secured on the underside of the cross car beam, behind the I/P compartment . The I/P compartment is the glove box ,don't know why they just don't say that . You could also check out the power and ground from the componet that's not working ! You can find factory like service info. from alldata http://www.alldata.com/ . Check out some videos on youtube https://www.youtube.com/watch?v=efKoWifdcag&t=224s Interior Lamps Dimming The second group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination and of incandescent lamps. • The door switches and the window switches • The HVAC control head assembly • The radio • The instrument panel cluster (IPC) • The steering wheel controls • The heated seat switch • The HUD switch • The lift glass window release switch and traction control switch When the ignition switch is turned to the ON position, the vacuum fluorescent (VF) displays (radio and HVAC control assembly), incandescent lamps, turn on at maximum brightness. When the park lamps are on and the ambient light sensor indicates low light conditions, all incandescent back lighting turn on at the dimming level indicated by the IP dimmer switch. At the same time all vacuum fluorescent (VF) displays dim to match the indicated dimming level. The BCM L fuse in the console fuse block, supplies battery positive voltage to the BCM. The I/P courtesy lamps supply voltage circuit of the BCM, supplies battery positive voltage to all the dimmable lamps. When the headlamp switch is placed in the PARK position, the BCM will then dim the interior lamps to the dimming level indicated by the IP dimmer switch. When the driver selects a dimming setting by moving, the IP dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. The incandescent back lighting lamps are then grounded at G200, G301 and G302. When the IP dimmer switch is moved from MIN to MAX, all vacuum fluorescent (VF) displays, as well as all incandescent back lighting respond from Minimum intensity to maximum brightness in response to the IP dimmer switch. The driver may select parade mode by manually turning on the park lamps during daylight conditions. The front park lamp circuit supplies voltage to the instrument panel cluster, radio and HVAC assembly for a park lamp on input, and the displays will become full bright.

You need the code number.....or perhaps a dealership can help you....

To find out testing the electrical circuit would need to be done ! Videos on youtube ! Is it manual or automatic climate control ? Blower Motor Problems Auto Repair Help
