How to Remove the Car Air Conditioner Blower?
3 Answers
Car air conditioner blower removal method: 1. Unplug the blower power connector; 2. Remove the blower limit screws; 3. Hold the blower and rotate it to the left to remove it. Precautions for removal: 1. Turn off the vehicle power before disassembly; 2. Do not let foreign objects fall into the blower. The car air conditioner blower is mainly composed of a motor, air filter, blower body, air chamber, base (also serving as an oil tank), and oil drip nozzle. The blower operates by the eccentric rotation of the rotor inside the cylinder, changing the volume between the blades in the rotor slots to suck in, compress, and expel air. During operation, the pressure difference of the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise, while preventing gas backflow in the cylinder.
I remember helping a friend remove the air conditioning blower from his car before. The whole process was time-consuming but not too difficult. First, disconnect the negative terminal of the battery to prevent electrical shorts. Then locate the glove box area, as the blower is usually located under the dashboard on the passenger side. You'll need to remove the glove box screws and clips to take out the entire glove box, which may require a screwdriver and wrench. Next, you'll see the blower assembly with its power cable and mounting bolts. Gently unplug the power connector, unscrew the bolts, and the blower can be slowly pulled out. Be careful not to use excessive force, as the blades are fragile and can break easily. If the blower is faulty, simply replace it with a new part. For dust cleaning, just use a soft brush to clean it thoroughly. The whole process took me about two hours. I recommend doing it on weekends and avoiding starting immediately after driving to prevent excessive heat inside the car. After completion, remember to test the AC and listen for normal operation sounds.
When I noticed the AC vents had weak airflow and loud noise, and decided to remove the blower motor, the first step was ensuring safety: turn off the engine, remove the car key, then disconnect the negative terminal of the battery to avoid electric shock. Next, on the passenger side, open the glove compartment, remove its mounting screws and inner clips. After taking off the glove box, the blower motor housing will be exposed. Be careful when unplugging the power connector—don’t yank it. Use pliers or a screwdriver to slowly loosen the screws securing the blower motor bracket. The blower itself might be clogged with dust or hair; clean it thoroughly before reinstalling. For beginners, it’s best to prepare tools like a screwdriver set and gloves to prevent scratches. The process isn’t difficult but requires patience—last time it took me an entire afternoon. After reassembly, start the vehicle and test if the AC airflow has returned to normal.
