Jeep Cherokee, A/C kinda cold, random high side pressures

CJ51974 on Sun May 31, 2009 9:23 PM User is offline

Year: 2002
Make: Jeep
Model: Cherokee Larado
Engine Size: v6
Refrigerant Type: 134a
Ambient Temp: 65f
Pressure Low: 20-40
Pressure High: 100-120
Country of Origin: United States

I have a 02 Grand Cherokee Larado, 6 cyl recently bought the vehicle. The a/c is kinda cold, not great. The low side cycles between 20-40, and the high side 95-120psi. However randomly every couple times the compressor clutch kicks on it the high side will be around 200-210 psi. The pressure before start up is 70. Can anyone help me? The high side is just so random. Thank you.

You might be low on refrigerant, only way to tell though is to have it reclaimed and then refill into a deep vacuum the proper amount..Hope this helps..
