My 2019 Jeep Cherokee Latitude + is having AC issues. When I turn it on at any setting, it will run for a little while. During that time, the air blows strongly and then weakens; it alternates between these. Then, the air completely stops blowing but the AC system is still on. Any ideas? It's way too hot in New Mexico to be driving around with no AC.

Try using "AUTO" A/C mode. When in "AUTO" the system has a mind of its own. Try using the "AC" mode button. Adjust the temperature up and down. Change the fan speed. Has the cabin air filter ever been changed? One time I didn't sync driver and passenger settings and set drivers side to AC and the passenger side to HEAT, the poor HVAC system went crazy trying to fight itself. Check how you have set the Uconnect settings. I have a 2014 so 2019 may work differently. Refer to your 2019 Owner's Manual and follow the instructions. If some feature does not work according to how the Manual says they should work then go to your Jeep dealer and have them fix it accordingly.
And, my usual rant: get your battery tested for free someplace. I know from prior bad experiences that batteries do not like heat. The HVAC system puts a real strain on the battery and alternator. Personally I only recommend the X2 Power AGM battery from Batteries Plus Bulbs.
This is my attempt to improve battery life: Service Transmission light ON 2014 TH
Probably not necessary where I live, moderate temperatures all Year. Back in the last Century I would actually go to Phoenix, AZ in August, it was brutal.
My X2 Power battery goes out of its 5 Year Warranty period next week. Just had it tested twice and the CCAs are the lowest they have ever been, but still ok. I don't have ESS which is a great battery saver.
My other 'trick' is whenever I stop the Jeep I immediately open the engine hood to let the heat out.
When I am off road I always use the AC and never turn the engine OFF while I am out of my Jeep for any reason.
Once you turn the Jeep OFF it is a crap shoot if it will actually restart again.

If a 2019 is your new Jeep then you must have bought it used. Have your Jeep dealer print a VIP report and review it with you. Look for any HVAC issues. Get a CarFax report for free someplace. Look for any old issues of concerns.
