Hello i am schleck the problem sounds like deminished air flow do to #1 trash or built up in between radiator &a/c condenser to gain enterance to the build -up you must remove upper fan shroud and rinse clean with water.#2 the radiator fan clutch is the second most common to check start engine up warm to operating temp,compare fan speed to engine speed should look the same also the air going through the shoud be very hot.#3 restricted coolant flow in side radiator.good luck!

I have ford mustang 1999 when i start my car and


there will be a cooling fan in front of the condenser ( ac unit in front of the radiator) that should be running as soon as you turn the ac on. If that is not working then the head pressures for the compressor become excessive and to save the compressor from damage it is shut of at the clutch at the pulley. When you are moving there is air flow through the condenser and so the head pressures are maintained at the correct level. Have it checked out by an accredited auto ac specialist . If you have a viscous fan hub on the engine fan the consider replacing it as it is not pulling air through the radiator when idling

Suburban overheating and air conditioner blowing hot


If you have a viscous fan hub have it replaced as it is not working. The problem you have is that the engine is not driving the fan to draw air through the radiator when idling so the engine overheats . When moving the air flow from driving cools the radiator and so the temp goes back down. If you have electric fans have the codes read to find the fault or check why the electric fans are not working.

2000 ford taurs a/c dont work it blows cold when i power up the compressor.its running 45 lbs on my gage on the low side.


Hi...
Perform the following basic Checks and Information
1. Check Drive Belts,If belt is intact proceed to the next step.
2. Check for Compressor Clutch Engagement - Turn the air conditioner to the "on" position and set controls to the coldest setting. Start the engine and allow to idle. Then open the hood and inspect the clutch at the front of the compressor, is it turning? "Engaged" if so, the system has enough refrigerant to activate. If the system is low on refrigerant it will not work properly. In this case an air conditioner recharge kit is needed to recharge the system. If the compressor clutch is not turning proceed to next step.
3. Inspect for Refrigerant Leaks
4. Check under dash panel and under hood power distribution center
5. Check Temperature Control Vents - The vents inside your car are controlled by a cable, electrical servo or vacuum servo. If the vent door is not functioning properly it will cause warm air from the heater to exit the vents. To check this start the car and allow the engine idle, next turn the blower motor speed on low, switch the temperature control from warm to cold while your ear is close to the vents. You should hear the door move inside the heater box as it swings from open to close. If not, inspect for a vacuum leak or a shorted motor in the servo, repair the leak or replace the servo motor.
Thanks
Smith

2002 Suzuki xl7 Mysterious Overheating Issue


Most Suzukis A/C systems will cut out when the engine tempurature is too high (to reduce the load on the engine). Also, in this condition, when the A/C compressor cuts out, the A/C thermo fan (electric - in front of the condensor) may come on ( to try and cool the engine). Combined with the fact that your temp gage says the engine is hot, I would be checking your cooling system very closely. It could be as simple as leaves blocking the air flow through the radiator (between the condensor and radiator), or as serious as the internal cores of the radiator being blocked (different sorts of coolant being used can sometimes produce solid matter that can do this).
