Once you find the 2012 Grand Cherokee AC low pressure port cap, hook up the can of refrigerant to the low pressure port.

How do you recharge AC in a 2012 Jeep Grand Cherokee? The low side AC port location is the first thing to find when you are looking for how to put freon in a car. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. The A/C system in your Grand Cherokee consists of a compressor that is belt-driven, an evaporator and freon.

Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a freon. Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. When the air conditioner in your 2012 Jeep Grand Cherokee starts blowing hot air, you likely have a freon leak.
