6. Disconnect one-touch joints.
a. Set a disconnector [high-pressure side (SST: 9253089908), low-pressure side (SST: 9253089916)] on A/C piping.
b. Slide a disconnector toward vehicle front until it clicks.
c. Slide A/C piping toward vehicle front and disconnect it. CAUTION:
Cap or wrap the joint of low-pressure pipe 1 and high-pres-
sure pipe 2 with suitable material such as vinyl tape to
avoid the entry of air.
7. Remove blower unit. Refer to ATC-103
.
8. Remove mounting screws, and then remove air mix door motor (passenger side), mode door motor and evaporator cover.
9. Remove mounting bolt, and then remove low-pressure pipe 2 and high-pressure pipe 3.
CAUTION:
