My dealer wanted 450 just to charge the system being that it required r1234yf refrigerant. The faulty condensers were installed until October 2017 build date. Your and my suburban should be covered. The upgraded style has a long aluminum plate welded down the side at the dryer the old style I had is just 2 small stitch welds. What they began completing in October 2016 was adding a sticker to the upper right hand side of the condenser to try to spread out the pressure due to wind. This didn’t work and the special coverage was extended to 2019 models.

Received my 1/2” LH acme female to 1/2” acme male adapter. This allowed the yellow charge hose to connect to the R1234yf can tap. R1234yf constantly freezes the can so it took 1.5 hours to load 4 of the 8 oz cans into the system. You have to stop, shut the can tap valve and wait for the can to heat up. A/c works perfect again. System low side pressure of 55 matched the chart. Always remember to vacuum down the system for a minimum 30 minutes and leak test the system. The new Freon is way too expensive to waste.

New air drier with desiccant was included attached to the condenser so it is a package deal.

Yes. They said it is VIN specific. Even though my year and make are covered my VIN was not. I even had numerous calls with GM customer service and they told me I was SOL.

My repair is posted:

Everything went back together well. Hooked up my new gauges, pulled a vacuum for 30 min with no leaks, but found a problem. Closed valves installed my new 1/2” LH thread R1234yf can tap and went to hook up my yellow hose to the tap. Nope, yellow hose was RH thread. I guess the kit accidentally supplied the hose for r134a. An adapter was also supplied, but it was exactly opposite of what was needed. eBay seller should be responding to me soon, but be aware during corona virus next day air options are limited. California heat wave is coming so I guess I am stuck for a few more days. See attached pics of the tools and materials needed to charge the A/C system.

Replaced my condenser today. Simple repair: 1. Ensured all R1234yf has leaked out. New gauges purchased as the high and low pressure ports are different than 134a. 2. Shut off engine/remove negative battery cable. 3. Use 5/16” nut driver to loosen intake plenum and air cleaner. 4. Pull red clip up and depress black clip at airflow sensor connector. Remove zip tie clip from hole in air box, place MAF connector out of the way. 5. Depress 2 pcv retainers and remove crankcase piping from plenum. 6. Gently work the plenum to throttle body intake hose loose. Same thing with the hose at the air box. 7. Remove upper and lower air box/filter. 8. Remove 2 bolts holding radiator in place against the core support. 9. Remove the upper air dam (sits on top of condenser/ radiator). Has 4 clips across the top and 2 on each end. 10. Push radiator toward engine. Remove the caps and clips holding the integrated transmission cooler lines in place. 11. Remove bracket bolt on passenger end of condenser hose. Also remove the hose retaining nut releasing both a/c lines. 12. Release the plastic clips holding the condenser to the radiator. 13. Get another person to hold the radiator toward while you pull the old condenser out. 14. Transfer all air dam pieces to new condenser. 15. Add 2 oz pag oil designed for r1234yf to the condenser INSTALL IN REVERSE ORDER.

Bump, looking for some guidance!

Looking for some help here. I have a 2017 Suburban with a major refrigerant leak in the upper driver side condenser at the weld near the air drier. GM has special coverage on my year and make for this exact reason, but it does not apply to my VIN number. Is there any way to get this coverage to extend to my VIN? My truck is 14k mi out of bumper to bumper and I would complete the work myself except it is R1234yf refrigerant so I wouldn’t know where to start on the recharge process.
