Condition
Some customers may comment on one or more of the following concerns:
• Temperature control inoperative
• No heat
• No defrost
Cause
This condition may be caused by the air conditioning evaporator case not aligning with
the upper HVAC housing case, causing the control gears not to engage properly when
adjusting the temperature.
Correction
1. Check the temperature and mode cables operation as instructed in Service Bulletin
17-NA-113 (Document ID# 4694428).
⇒ If the gear mesh is lost during adjustment, replace the air conditioning
evaporator case.
2. With the cable detached, verify that the mode and/or temp doors move freely.
⇒ If the doors are sticking with the cables detached, replace the air
conditioning evaporator case.
Note: When replacing the case, a new cable retention feature has been added to
prevent kinking of the cable.

- R134a Replacement - Hydrocarbon blend that is 100% natural, safe for the ozone and non global warming. Chemically compatible with R134a systems.
- 6oz (11.7 fl oz) Cans - Compressed gas is measured by weight. This gas is light weight compared to others, but has the same "volume". Guaranteed that you will use no more than normal!
- SSV Cans - Self Sealing Valve allows for the storage of unused gas. Requires SSV compatible tool. Avoid "piercing" style tools or the gas may come out slowly or not at all.
- Disclosures - Product is flammable like many other modern refrigerants. Observe all precautions on the product lablel when handling and storing. Follow all legal requirements when charging your system. Hydrocarbon blend refrigerant for NON MVAC use in 6oz SSV Cans.
- REGULATED FOR LEGAL SAFETY: Approved for use in R134a systems only, in compliance with EPA regulations. It ensures proper functionality without the risk of mixing refrigerant types, providing peace of mind and legal safety
- HVAC Guys AC Refrigerant R134a Replacement - Eco-Friendly, 100% Natural Hydrocarbon Gas - R-134a Replacement for use in a 6-ounce self-sealing container
- Compatible with 1/2" ACME Self-Sealing Can Tap

- GREEN REFRIGERATION SOLUTION: ZeroR AC Refrigerant is a 100% natural hydrocarbon gas, offering a more eco-friendly alternative to traditional AC recharge like R134a. It helps reduce environmental impact while providing reliable cooling performance
- R134A READY INSTALLATION: Designed to fit R134a systems, ZeroR AC Refrigerant installs just like any standard refrigerant. The cans feature R134a-compatible threads, ensuring easy and seamless installation with your existing R 134a refrigerant can taps
- SMALLER CAN BIGGER IMPACT: Each can of our car AC refrigerant holds 6oz of refrigerant, but its performance is equivalent to 16oz of R134a. This makes it a highly efficient and cost-effective option, requiring less product while maintaining excellent performance
- BUILT FOR SAFE USAGE: ZeroR AC Car Refrigerant is rated with a class 2.1 rating, similar to newer refrigerants like R1234YF. When used in systems designed for refrigerants, it’s safe and poses no danger to users under normal operating conditions
- REGULATED FOR LEGAL SAFETY: ZeroR AC Recharge Can is approved for use in R134a systems only, in compliance with EPA regulations. It ensures proper functionality without the risk of mixing refrigerant types, providing peace of mind and legal safety
- High Quality Material: This car AC refrigerant charge hose is crafted with high-strength aluminum material, which strong pressure resistance and corrosion resistance, not prone to deformation, extending the service life of the hose. Meanwhile, aluminum material has good thermal conductivity, which helps to quickly balance the temperature of the hose and the environment during filling, reducing pressure fluctuations caused by temperature differences and improving filling accuracy.
- Widely Application: This product measures of 15.4 inches total length with 0.51 inches diameter low side quick coupler and 1/2 inches dispensing valve. This kit can be used for automotive air conditioning systems with R134a, R12, or R22 standard interfaces. Suitable for most vehicles such as sedans, SUVs, trucks, vans, etc. Note: Not compatible with 2018 cvic, tuscson.
- Simple Installation: This car AC refrigerant charge hose is designed to be easy-to-install. First, connect the self-sealing dispensing valve to the refrigerant can. Then, connect the low-pressure side quick connector to the interface of the R134a automotive air conditioning system. Finally, open the low-pressure valve, slowly add refrigerant, and observe the pressure gauge reading.
- Practical Functions: This kit equipped with a pressure gauge, it can monitor the pressure of the air conditioning system in real time, determine whether there are any abnormalities, assist in troubleshooting, and also achieve quantitative charging through the control valve to avoid overcharging or undercharging. While the high-precision threads processed using CNC cutting technology provide better sealing when used with R134a valves.
- Complete Package: This product package contains a pair of R134a refrigerant recharge hose with gauge, one side is R134a low side quick coupler, another is 1/2 dispensing valve. This kit features a user-friendly design that allows you to release the refrigerant tank with one hand, without needing to use both hands. The extended hose allows you to easily reach deep into the engine compartment, making it the ideal choice for quickly replacing aging valve cores.
