Why does my Jeep overheat when the AC is on?
Well if it’s your AC that causing you to overheat then to me that means your cooling system is marginal and the increase in heat load from the AC is overloading it. Start as instructed above and see where you are coming up short. Look hard at the fan clutch if it’s at low speed and the rad if at hwy speeds.

Is there a problem with my Jeep Liberty?
The gauge shows it is fine, but the warning light comes on, and the Jeep stops…..push the gas, the engine revs up, tachometer climbs, but the Jeep won’t move.
