Generally at idle if the system blows hot air is because air is restricted to the condessor coil which is mounted on the front of radiator. the solution to this is to power wash the dirt bugs and road grime from it this will alow the air to flow over the coils and fins. also mmake sure that the system is fully charged and the pressures are good the low side should be about 35 psi and high side should be about 120-150 psi for a 134a system also make sure that the a/c clutch relay is not weak this is found in the junction box under the hood. if the pressures are way off this could mean there is a obstruction or a leak and then it should be serviced by a qualified technician. good luck please rate this solution thanks

your electric fan for the AC is not working for whatever reason so when idles its all getting hot the engine and the AC system .This sort of work can be difficult to diagnose correctly and a code reader is about as good as a bible at mosque so seek the advice of a skilled mechanic who should be able to pin point the fault in seconds

When you stop at a stop sing heater blows cold air


Check your coolant level, low fluid can cause this. Check level with engine fully warm, heater on high. Check your manual to see if you have any air bleeds, these soemtimes look like grease fitting, and are located at higher spots in the cooling system.

When my 2006 elantra is idle the hot air blowing out turns cold. Is this a common issue? What is the solution?


These cars use a thermostat that has a little check ball in it to let hot water past the thermostat to warm the interior even if the thermostat is not opened up yet. The ball could be sticking. Another possibility is that the fins on the water pump have corroded away, but your car isnt that old for that to have happened( I would hope) unless you have had your coolant replaced and whoever replaced it used city water instead of distilled water. Some water is acidic and could corrode internal parts. Alway use distilled water in a cooling system along with antifreeze.
Or you may have a loose water pump belt and at idle it is slipping.

Poor functioning A/C in 2004 GMC Sierra 1500


Have the engine fans and relays checked. If the engine fan does not come on when the a/c compresser kicks in then the air that comes out the vents will be warm.

Elantra 2001, A/C compressor clutch engages and disengages every 2 sec.When i first start the engine I got cool air then, after the engine is hot, the problem starts and bye bye cool air!


The a/c clutch engages then disengages intermittently with the Hyundai's a/c system when there is little or no refrigerant in the system.

Have your a/c refrigerant (R134 or R12) checked and refilled, and have the system inspected for leaks.

Hope this helps.
