How to retrieve something dropped in car air conditioning vent? Use a Phillips head screwdriver. Push the armrest forward. Unclip at the top and bottom. Use the screwdriver on each corner. Unclip the 2 clips at the top. Each vent has a RH or LH. Unclip the 2 clips at the front. Push them down a little.
Use a Coat Hanger: Straighten a wire coat hanger and create a small hook at one end. Carefully insert it into the vent to try to snag the object. Vacuum with a Hose Attachment: If the object is small and can be safely vacuumed, use a vacuum cleaner with a hose attachment to try to suck it out.
Use a Vacuum: Take the hose of your vacuum and insert it as far as possible into the duct. Turn on the vacuum and move the nozzle around. Check the vacuum canister for your lost item. You can also try putting pantyhose around the vacuum opening and secure with a rubber band.
Use a soft brush attachment on your vacuum cleaner to gently suction out any visible debris from the vent slats. For stubborn blockages, a can of compressed air can dislodge dust and small particles from deeper within the vents.
Cleaning the car's ventilation system
Turn the ignition on, turn the heater blower up to full speed and open the vents, one at a time. This will blast the dust out of the system. Once done, give it 10 minutes for everything to settle and then start vacuuming up the dirt that's been dislodged.
Bend the person over at the waist to face the ground. Strike five separate times between the person's shoulder blades with the heel of your hand. Give five abdominal thrusts. If back blows don't remove the stuck object, give five abdominal thrusts, also known as the Heimlich maneuver.
Most air vents have a small lever or dial on the side that allows you to open or close the fins just underneath the cover. When the fins are closed, air won't flow through the vent into the room. When they're open, air can move freely.
The vents can be adjusted to point at the faces of the front-seat occupants. Some cars also have ducts to the rear-seat area. Slots in the ledge at the bottom of the windscreen - and, in later cars, by the front side-windows - allow a stream of warm air to be blown on to the glass to prevent misting.
Use a Hoover
If the object is out of reach, or close to a fan or electrical item, then you can use your hoover to suck the item back to the surface. Place the vacuum nozzle into the vent close to the location of the object, and suck it up.
Brush away dead leaves or any other accumulated debris using a broom or handheld dust brush. Spray inside the vents with a sanitizing enzymatic cleaner. Enzymatic disinfectants will help kill mold or fungi growing in your vent system, while air fresheners will just act as a perfume.
Either it's not getting electrical power or, more likely, the motor itself has simply burned out. A blower motor in an older vehicle is likely to burn out over time, and may need replacement.
Put the glass with the handpiece into the water-filled ultrasonic bath. If possible, set the temperature to 50°C (122°F) and activate the ultrasonic power at your usual setting for approximately 15 minutes. Rinse the AIRFLOW® MAX handpiece with tap water.
Signs of an air duct clog include: One room in your house is hotter than all the others. Dirty air coming from vents. Unusual spikes in electric bills.
The cough is helpful, and it may clear up the problem. Inhaling a substance into your lungs can cause lung inflammation and an infection (aspiration pneumonia). The situation may be more serious when a person: Has signs of choking (complete airway obstruction).
Only wash out the ear canal if you don't think there is a hole in the eardrum and no ear tubes are in place. Use a rubber-bulb syringe and warm water to wash the object out of the canal. Don't use water to remove batteries, food or plant material. Use oil or alcohol for an insect.
Remove loose debris: Use a leaf blower or air compressor to blow away the majority of loose dirt and debris from the engine bay. Dry brush: For the hard-to-reach places and any areas not cleared by a leaf blower or air compressor, use a soft brush to loosen dirt and grime from the surface.
Most cars have single exhaust pipes, while some have dual exhausts. After regular intervals, it is important to clean the pipes using only water or water and soap to remove dust and debris. For deeper cleaning, you may use a long stick brush and penetrate it inside the pipe and clean thoroughly.
