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.
