Wynding noise under dash when picking up speed.

Sounds like a ground issue or the voltage regulator is on its way out

Since it should be under factory warranty I would expect you to take it to the dealer for inspection.
My first guess would be something in the exhaust or the suspension.

These lights for the dash are controlled by a rheostat instrument control dimmer switch next to the main light switch for the headlights, it is either turned off (have seen this dozens of times) or it is defective. Below is a picture of the switch assembly I speak of. The thumb wheel next to the knob is the dimmer control.

You need to replace flasher unit. This regulates the flashing speed. Check under the drivers side dash (it may hang amongst wires or in a fuse box) or under bonnet where all the large fuses are (these will be in a covered box). Sounds like under dash because of noise. Google search flasher units to see what the look like.

clunking noise front when turning left and does it right also but not as bad 2006 g6 at low speed and goes away as you speed up but always there i have replaced lower control arms both side still there

It is under the right side of the dash. Blower resistor and relay.

Your wheel bearing is the fault.Get it changed ASAP.Good luck hope that was helpfull.

Must be a bad front wheel bearing. Does the pitch change as you speed up and slow down?

fan elays are under hood in black box by battery. 3 of them. 2 for high speed, 1 for low speed. Default is high speed when there is a probem.

Suspect maybe they shorted something out when fixing dent. Did they do any welding on the van? Connecting the cables to the body can sometimes send voltage where it's not wanted.

Check the fan assembly probably located behind your glovebox. The fan could be off-center.
