Condition

Some customers may comment that the A/C blows warm air.

The technician may find low or empty refrigerant in the system.

 

Cause

This condition may be caused by a leak at the A/C condenser receiver/dehydrator tank plug.

 

Correction

Note: The Receiver/Dehydrator Plug can be found in the lower left side of vehicle. For clarity, the condenser shown below is out of vehicle and up-side down.

 

Note: Due to possibility of the new/replacement desiccant being compromised, replace ONLY the Receiver/Dehydrator plug until further notice. Do not open the A/C system until the replacement part is at the dealer.

  1. Inspect the AC Condenser (1) and inspect the receiver/dehydrator tank plug (2).
  2. Add A/C dye to verify that the leak is coming from the plug.
  • If refrigerant has been validated to be coming from the tank, replace the plug using a desiccant kit.
  • If no signs of leaking have been found, refer to SI for further diagnostics.

ZeroR® AC Refrigerant | R134a Replacement | 6 Cans for AC Recharging
  • UNIVERSAL - ZeroR AC Refrigerant is a hydrocarbon that safely bonds with chemicals like R134a, R1234YF and R12. We can only advertise this product to be used in R134a systems due to EPA regulations in the USA on both R12 and R1234YF systems. EPA also prohibits mixing refrigerant types. See the description for all legal disclaimers.
  • EASY - This product installs just as easily as any R134a products. Cans even have R134a threads and the majority of R134a can taps will work for these cans.
  • 6oz CANS - Refrigerants are compressed gasses and are measured by weight, not by liquid volume such as water. All gasses compress differently and produce a different weight. ZeroR AC Refrigerant is low weight compared to R134a, but its performance is equal to 16oz of R134a.
  • ECO FRIENDLY – ZeroR AC Refrigerant is a 100% Natural gas unlike R134a, R1234yf and R12.
  • SAFE – ZeroR AC Refrigerant has a class 2.1 flammability rating just like the new R1234YF which is now used in 100% of newly manufactured vehicles. Under normal operating conditions this product presents no danger to its users when handled properly and used in systems approved for flammable refrigerants.

Leak Saver 134a Replacement Refrigerant for MVAC, HVACR, Automotive - R-134a for MVAC use in a 8-Ounce Container - 3 Pack
  • WORKS WITH ALL 134a SYSTEMS: Our 134a Replacement Refrigerant is compatible with all systems and lubricants that are designed to be used with 134a refrigerant or that have been retrofitted to use 134a. It can be used in cars, trucks, refrigerators, RVs, boats, tractors, combines, ice machines, milk processing equipment, and any other equipment calling for R-134a. You must follow all EPA guidelines when handling this refrigerant.
  • COLDER FORMULA WITH LOWER HEAD PRESSURES: Our refrigerant is a specially engineered hydrocarbon formula that operates at a lower head (high side) pressure than standard 134a. This can allow your compressor to run smoother and have improved cooling and performance properties. This is our coldest and highest performing refrigerant formula. When charging, our 134a Replacement Refrigerant is easily installed using the same pressure parameters as standard 134a.
  • USES LESS REFRIGERANT BY WEIGHT: Our 134a Replacement Refrigerant is physically lighter than standard 134a refrigerant. Each 8oz can of 134a Replacement Refrigerant is equal to 21oz of standard 134a refrigerant (a 1:2.6 weight ratio). That means that if you want to add 12oz of standard 134a refrigerant to a system, you will only need to add 4.6oz of our 134a Replacement Refrigerant. This translates to using up to 60% less refrigerant for a proper charge.
  • PROVEN FORMULA THAT IS ENVIRONMENTALLY SAFE: The Leak Saver 134a Replacement Refrigerant formula is 100% USA Made. It is designed to be a climate-friendly green alternative to standard 134a and is non-ozone depleting and has zero Global Warming Potential (GWP). On the other hand, standard R-134a is an HFC (hydrofluorocarbon) greenhouse gas and has a high (GWP). Please note that this refrigerant is flammable and has been safely sold for all the listed applications for over 28 years.
  • YOUR SATISFACTION IS OUR PRIORITY: We stand 100% behind the effectiveness of our products. If for any reason you are not satisfied with your product, please contact us, and we will make it right.
