COMPONENT DESCRIPTION
Air Mix Door Motor
The air mix door motor is attached to the A/C unit assembly. It
rotates so that the air mix door is opened or closed to a position set
by the front air control. Motor rotation is conveyed through a shaft
and the air mix door position is then feedback to the front air control
by PBR built-in air mix door motor.

< PRECAUTION >[AUTO AIR CONDITIONER (W/NAVI)]
PRECAUTIONS
- Do not allow A/C oil to come in contact with styrofoam parts. Damage may result.
CONTAMINATED REFRIGERANT
If a refrigerant other than pure HFC-134a (R-134a) is identified in a vehicle, your options are:
Explain to the customer that environmental regulations prohibit the release of contaminated refrigerant into
the atmosphere.
Explain that recovery of the contaminated refrigerant could damage your service equipment and refrigerant
supply.
Suggest the customer return the vehicle to the location of previous service where the contamination may
have occurred.
If you choose to perform the repair, recover the refrigerant using only dedicated equipment and contain-
ers. Do not recover contaminated refrigerant into your existing service equipment. If your facility does
not have dedicated recovery equipment, you may contact a local refrigerant product retailer for available ser-
vice. This refrigerant must be disposed of in accordance with all federal and local regulations. In addition,
replacement of all refrigerant system components on the vehicle is recommended.
If the vehicle is within the warranty period, the air conditioner warranty is void. Please contact NISSAN Cus-
tomer Affairs for further assistance.
Precaution for Service EquipmentINFOID:0000000001547384
MANIFOLD GAUGE SET
Be certain that the gauge face indicates R-134a or 134a. Make sure
the gauge set has 1/2″-16 ACME threaded connections for service
hoses. Confirm the set has been used only with refrigerant HFC-
134a (R-134a) along with specified oil.
SERVICE HOSES
Be certain that the service hoses display the markings described
(colored hose with black stripe). All hoses must include positive shut-
off devices (either manual or automatic) near the end of the hoses
opposite the manifold gauge.
SERVICE COUPLERS
Never attempt to connect HFC-134a (R-134a) service couplers to a
CFC-12 (R-12) A/C system. The HFC-134a (R-134a) couplers will
not properly connect to the CFC-12 (R-12) system. However, if an
improper connection is attempted, discharging and contamination
may occur.
