If you have checked refrigerant pressure OK, then I don't think there is a problem with the new AC. One of several problems leading to the situation to be addressed in the following order to take care of this problem:
1- The flap valve diverting air direction from heater core or evaporator as desired has a problem with its position due to valve control problem.
2- There is a coolant temp sensor bad causing erratic value to the control so it can turn on and off the AC clutch.
3- There is an evaporator sensor to give a feed back to climate control to stop AC if it is too cold.

1995 JEEP WRANGLER 2.5L HARD START COLD 1 START OF THE DAY


When you're trying to start it for the first time of the day, look at the dash to see if the check engine light is on when you first turn on the ignition. If the check engine light is not lit up, your Jeep ecu is in need of repair and the vehicle will not start until that check engine light finally comes on.

1995 Jeep Wrangler 2.5L Fuel Pump/Check engine light


Could be one of several items...I'd check the fuel pump relay, auto shutdown relay and the ignition switch itself. I'd bet on it being one of those relays but, we all have been fooled at least once!!! I'd also make sure that body and engine grounding is good and clean. Relays can't work properly without a good ground.

1998 Jeep Wrangler a/c problem


what this means is that either you have a low charge or your expansion valve is failing to operate properly. the expansion valve regulates the ther system which in turn allows the clutch to kick in . 4-5 years is generally the time a system needs a recharge anyway because the refrigerant starts to break down and the system no longer meets the minumum pressures. plus your dryer element most likely needs replacing as well thats where you get the smell from the crystal pellets inside the dryer are no longer any good

2002 jeep wrangler OVER HEATING


Run it for a while and check the two heater hoses to the fire wall for the heater core. Turn the heat inside on low and floor. The hoses (when the jeep is hot) should be about the same temp. One will be slightly cooler than the other one. If this is not the case and one is much colder than the other you have a plugged heater core. Mark the cool hose let the jeep completely cool remove the cold hose and the hot hose use a garden hose to flush the core in direction of the cold side to hot side. If this is not it you have a air pocket in the system or your blend doors in the air box under your dash are broke.

1992 Jeep Wrangler heater not blowing hot air


How often has the coolant been changed? My only guess is that it hasn't and the hoses and the heater core are plugged up with goo and a flush is needed

Jeep Wrangler 03 A/C stopped working abruptly


This may be the AC compressor cycling switch is defective. It is located in the larger of the 2 AC lines coming from the compressor, it has a wire connector to it with 2-3 wires. To verify this is the issue jumper the connector with a small piece of wire and see if the compressor runs.
