How do you recharge air conditioning in 1999 Jeep Grand Cherokee?

Answer 1

To recharge the air conditioning in a 1999 Jeep Grand Cherokee, first locate the low-pressure service port, usually found on the larger diameter AC line. Attach a refrigerant can with a gauge to the port, ensuring the engine is running and the AC is set to maximum. Open the canister valve and monitor the pressure gauge, adding refrigerant until the appropriate pressure is reached, typically between 25-45 psi, depending on ambient temperature. Always check for leaks and consider having a professional evaluate the system if problems persist.
