Why do my headlights brightning and dimming 2007 yukon?

Headlights dimming and brightening indicate a change in output voltage from alternator, not a problem as long as its within certain guidelines, usually 12.4volts - 13.6 volts (approx) . Overcharging alternators will produce a rotten egg odour from battery as it dries out. Put a voltage metre on the enging at idle and check upper range .

The DIC in my yukon 2007 ask me to check the left front tire pressure, and the DIC shows the pressure is 52, but the actual pressure is proper, whats the problem and how i can fix it.

sounds like you will need a new sensor that sits inside the tire at the valve stem.. some are costly some are not.. will require a tire machine to replace..

Yukon makes loud noise when backing out and turning steering wheel

If the noise is coming from the engine compartment then you may just be low on steering fluid.

Can you describe where the noise is coming from and what it sounds like?

Is is more of a grinding, or more of a whining or humming?

After I turned off my yukon there is a humming noise under the vehicle it sounds like the fuelpump is stillrunning whatcan that be

Automatic suspension leveler. If it only makes this sound for a minute or two then quits, it is normal and is adjusting the air shocks in the rear. If it makes this noise for hours, you have a bad air shock or leaking air line.
