Eliminate abnormal noise in the instrument panel and repair the servo motor operation of the old Aohu air conditioner wind direction flap (multi-text)
KyleEdison 
9 The gurgling sound in the dashboard has been twittering for many years. After reading many maintenance cases, it is determined that the abnormal noise is mainly caused by the wear of the annular resistance disk of the wind servo motor, and an old servo motor is used on the Internet. Only its annular resistance disk is used to replace the worn original car. After installation, the motor runs slippery and the abnormal noise is completely eliminated.
It is not difficult to tear it down, but it is troublesome to reinstall it. The difficulty is that when reinstalling, the three tracks of the pull-out plate are completely consistent with the three drawing heads on the box, and the wind direction mode instructions can be carried out accurately.

Remove the seat, you can completely lie down, turn around and lie on your side, the operating space is very comfortable.
If you put on a sponge pad, it will become a luxurious workshop, and you can lie down and rest when you are tired.
After removing the outer guard plate, the first part to be removed inside
You can see the assembly, the position of the four screws to be removed, No. 1 open demolition, No. 2 semi-blind semi-bright, No. 3 and No. 4 completely blind removal.
Disassembly and disassembly tools: short handle cross batch, strong soft magnetic absorption, electrical glue.
It’s out. The position of the four screws.
The assembly has two servo motors, the one with warm and cold air is ignored.
Turning over, there are three slides in the wind direction and a pull rod in the cold and warm air servo motor.
The three drawing heads on the box correspond to the three tracks on the assembly puller, and 4 and 4 correspond.
Before disassembling the motor, mark the gap position of the original car pull-out shaft on the shell.
Wear-through of ring resistance of original car parts
The quality of the contact is very good, it looks very rest assured.
Contrast, Tao Lai’s contact is too that, do not rest assured, decided not to use.
The motor of the original part is good, and the other two gears are intact, so only the ring resistance disk is replaced.
Install the resistance plate and apply a little grease on several gears
The gap of the shaft is well aligned with the mark on the shell, but the pull-out plate and the drawing head can not completely match during reinstallation, and the assembly cannot fit closely with the box. After studying for a long time, it is confirmed that it is caused by the failure of the No. 1 drawing head to enter the rail, and then disassemble the motor, adjust the pull-out angle, and finally a slippery match.
When reloading, screw No. 2, No. 3 and No. 4 should use electrical glue to stick the screw head on the screwdriver, otherwise it is easy to drop the screw when it is installed blindly, and the electrical tape will come out when you pull out the screwdriver after putting on the screw.
Important note: cut the wind mode to this mode before disconnecting the power.
Take apart the panel to visually confirm that the flip plate is open.
At this time, the corresponding No. 2 pull-out head should stop at the tip of the arrow, but it can be manually pulled in place, it will not rebound, pull there will stop there, No. 1 and No. 3 pull-back head have springback, ignore.
In the picture, the position where the No. 2 pull-out head stops is when the front wind turns the plate completely closed.
In the picture, the position where the No. 2 pull-out head stops is when the front wind turns the plate completely closed.
After some exploration and debugging, finally successfully installed, driving the air conditioning test, the abnormal noise is gone, the wind mode conversion is silky and accurate, although the problem is small, it is really not easy to solve it, the body is tired like a dog, the heart is very happy, a sense of achievement, this may be the fun of DIY.
Key points: first, before reloading the box, plug in the assembly, screw the key to ON, press the wind mode button, and cut off the power to the front outlet mode, which is consistent with the mode before opening.
Second, when reassembling, the assembly has the corresponding installation position with the box, but it is not sure whether the pull-out plate and the pull-out column are aligned. If the position is aligned, the assembly is closely seamed with the box, it is possible that the pull-out and the pull-out column are aligned, at this time, first put on the No. 2 and No. 3 screws, connect the wire, and turn the key to ON (no fire). Press the wind direction mode button to observe whether each rotation of the pull-out pan is slippery. When blowing to the front, observe whether the corresponding flip plate is open, if all ok, then fix No. 1 and No. 4 screws, and finally start empty debugging.
