Hear a sloshing sound when driving on my 2006 Infiniti m35

SOURCE: Infiniti M35 - change headlight Bulb

Take the wheel off the side with the burnt out bulb. Next pull the 6 plastic rivets out of the front fender well shield. Take the screw out of the shield above the 3 rivets along the inside of the fender edge, Pull the shield back starting at the top where it's tucked under the back portion of the liner shield. Unscrew the top plastic cover, twist the connector counter clockwise and pull it off the bulb. Then unclip the bulb and pull the bulb out noting the groove position for reinstalling the new bulb in the housing. There is nothing simple about your bulb change. The dealer price of the bulb is around $245.00. Don't break the new bulb trying to guess when it's seated properly!

if the refrigerant has leaked out (the system is below a certain presure). the a/c won't run to protect components. you need someone to check the system for refrigerant level (which means taking what's inside out) and checking for leaks.

SOURCE: Headlight adjustment for 2006 Infiniti M35

The adjustment screws/nuts should be located either on the top of the headlamp assembly, behind the headlamp assembly, or near the frame rail by the radiator support.

You will have vertical adjustment screws for each independent beam (separate highs and separate lows, but will be same screw if highs and lows are the same bulb). You may also have additional horizontal adjustment screws as well

Park your car on a level ground 30 feet from a wall and measure the height from the ground to the bulb and mark on a wall (do this for highs beams and low beams if the bulbs are separate, if highs and lows are the same bulb, only do it for the lows)

For Low Beams: If the headlights read VOR, then aim the brightest part or cutoff part just below the mark on the wall. If it says VOL or nothing, aim them 2 inches below the mark on the wall.

For High Beams (if separate from low beams): Aim the headlight directly at the line you marked on the wall.
