Condition Some customers may comment that the A/C is blowing warm, is exhibiting poor performance or of a general lack of air conditioning, or low charge.
Cause
The cause of this condition may be that, during operation, the auxiliary evaporator blower motor may emit brush dust that contains some copper particles. These particles could lead to accelerated corrosion to the auxiliary evaporator and a small refrigerant leak.
Additional Options Equipped with Auxiliary Air Conditioning (RPO CJ2)
Correction
After performing normal SI diagnostics, if the source of the leak is not found, check for a leak at the auxiliary evaporator core face. Remove the auxiliary blower control module and insert the GE 50078 Electronic Leak Detector to test for a leak, as well as employing the use of a black light.
If a leak is found, continue to the Service Procedure below to replace the evaporator, blower/fan assembly (if necessary) and thoroughly clean the interior of the evaporator case.
Service Procedure
4418319
1. Remove the auxiliary A/C evaporator (1). Refer to Auxiliary Air Conditioning Evaporator Replacement in SI.
4418321
2. Remove the auxiliary blower motor assembly (1).
Refer to Auxiliary Blower Motor Replacement in SI.
3. With the evaporator case disassembled, use compressed air to blow any copper dust from the inside of the case.
4418323
4. Use GM glass cleaner, P/N 19287404 (in Canada, 88865156), and a cloth to wipe down the linear power module and the inside surfaces, (1) and (2), of the case.
5. Install the new auxiliary A/C evaporator. Refer to Auxiliary Air Conditioning Evaporator Replacement in SI.
6. Inspect the auxiliary blower motor assembly to identify if it is an original motor or a replacement:

- UNABLE TO SHIP THIS ITEM TO CALIFORNIA and WASHINGTON
- Replaces lost R-134a refrigerant and oil in automotive A/C system to protect and extend system life
- Comes with reusable extra-long braided charging hose and large gauge with trigger dispenser for easy, convenient, and accurate recharging
- Formula with 2X cooling boosters vs the next leading brand of A/C recharge kits: independently tested to deliver the coldest air from your vehicle's A/C
- Contains R-134a gas which is acceptable for use in motor vehicle A/C (MVAC) systems
- 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.
- All in one solution to restore lost refrigerant and oil in automotive air conditioning systems
- Contains system safe leak sealer additive that seals common A/C leaks in rubber hoses, gaskets and O-rings
- Built in disposable recharge hose
- No tools required
- Safe for all R-134a systems when used as directed
- Approved for use in California
- High Mileage refrigerant for vehicles over 75, 000 miles
- Contains approximately 10 oz. of R-134a and 2 oz. of additives
- Contains leak sealer to seal common A/C leaks in rubber hoses, gaskets, and O-rings
- Contains high mileage No wear additives
- Replaces lost R-134a refrigerant and oil in automotive A/C system
- System safe stop leak sealer stops most common A/C leaks with hoses, gaskets and O-Rings
- Special anti-wear additives extend system life and improve performance
- Contains R-134a gas which is acceptable for use in motor vehicle A/C (MVAC) systems
- Complies with Section 612 of the EPA Clean Air Act, EPA Compliant in Self Sealing Cans
