How to change the three-cylinder Li Xia heater cylinder?

1. Disassembly sequence: 1, hand brake and shift fixed interior; 2. Storage box; 3. Audio host (player) and central control panel; 4. Remove the instrument; 5. Remove the steering wheel and combination switch. Methods Remove five screws placed under the wheel. After removing the panel, you can see a 2 1 nut in the middle. Some people say that the steering wheel can be disassembled, but my car can't. I didn't remove the steering wheel and combination switch, just put the steering wheel assembly on the seat and lifted the center console. I tried the method of "novices should be careful on the road" provided by students (there are two screws for fixing the steering wheel, and then look along the combination switch to the clutch pedal, and there are two screws for fixing the steering gear, that is, the steering wheel combination, just loosen these four 12 screws), so I lowered the steering wheel assembly to the seat. 6. Lift the center console. Remove four nuts under the windshield, two nuts under the storage box of the center console and one nut on the left and right sides of the center console with the sleeve of 10. (8 nuts of * * * 10), remove the relevant harness connector, and then lift the center console. 7. Lift the center console and you will see that warm air is always there. I mean the method provided by Liu Yibo. By the way, there are no screws on the heater assembly, but the steel plate is stuck. Second, the installation sequence is the opposite of disassembly. It took me quite a long time to put back the sponge around the original small water tank, but it was always difficult to put it back. I think it's easier to put the glue back when it's stuck. It took five hours to install the four screws of the steering wheel assembly, but I finally got the repairman to put them back in a short time. Now I don't know how to put them back. What is the secret?
