Kia picanto drive time ac good cooling traffic stop time not cooling

check that the fan for the condenser is working
with the vehicle moving the air flow will keep the compressor pressure down but when stationary and no air flow the gas pressure will go too high and the high pressure switch will stop the compressor
have it inspected by an accredited ac specialist shop

1999. Why is A/C air flow poor?

air flow from and air conditioner is dependent on the condition of the heater blower fan
so check that the blower fan is operating at all fan speed settings
next if you live or use the vehicle in dusty conditions , the dust will build up on the evaporator fins ( condensate water and dust = mud and gunk) and blocked evaporator fins ( this will result in reduced ac operation as well
the dust is not always from out side air through a cabin filter ( may be blocked) but from dirt that is introduced into the cab from dirt on the foot wear

Why does my pontiac torrent overheat when ac is on

sensors......Water temp sensor, air flow temp sensor, MAP sensor, Idle speed control solenoid, throttle position sensor, O2 sensor.........
Engaging AC draws on power from your motor, resulting in the ECU having to compensate to keep revs stable. Increased revs result in increased air flow, water flow, fuel flow & exhaust emissions.
Check belts for your AC pump first, as the same belt may drive your water pump. If it slips under load when the AC is on, ..................... Say no more. Next replace Water temp sensor. No luck..... ISC solenoid....

Air vent problem

ac evaporators inside a car become useless f the evaporator fins are blocked with a black greasy gunk
It will stop air flow from the blower motor and will not allow the air to be cooled as it passes through the fins
It is unlikely that there is a blockage in the vents
if a section of the ac evaporator box can be removed , check with alight and mirror to see all the fins are clean and if not , use an ac fin cleaner product to melt the gunk of the fins

No air coming out of the vents

It sounds like the heater motor may not be operating. When you switch the heater fan on can you hear the motor running? If not then it may have blown the heater fan fuse, check the fuse's and then try it again. If the fuse is ok then it could be a faulty switch or fan motor.

When i switch on the ac, no air come out

Sounds like the blower fan is not coming on all the time. Also check for circulation.
For the fan, you have a resistor which not be be making a proper circuit for the fan to work. If the fan resistor is okay, then the blower motor is the problem.
If the vehicle has a cabin filter check to see if it is plugged. Good Luck!

The ac won't work right

The first knob controls the temperature. Turning it counterclockwise will lower the temperature, clockwise will raise it. Pressing the button will turn on the circulate function (recirculates the air from the cabin).
The second knob controls the fan speed. Counterclockwise will reduce the fan speed, clockwise will increase it. Pressing the button activates the A/C compressor (allows colder temperatures).
The third knob controls the flow direction. Each picture indicates where the flow will go. Pressing the button activates the rear defoggers (in some models, it will also activate the heated side mirrors).
