Solution: 1. The engine has Idle Air Controller (IAC) that is suppose to keep the engine speed at a constant (even with changing load - AC, FAN, etc.) If the IAC is broken your idle will be rough or even die.
The AC compressor places a large load on your engine.If there is a problem with your IAC(Idle air controller)which is located on the throttle body it will cause the vehicle to die when you turn the AC on.Remove the IAC and check it for carbon.If there is carbon try to clean it up with a wire brush.
2. If your air con is drawing more power than your alternator/battery is capable of supplying - you could try fitting a higher charge rate alternator and a heavy duty battery also ensure battery to chassis earth is sound and clean of rust and grime at metalwork.
3.Another reason for this is that when the air con is on, ice and water forms on the outside of the air con pump and condenser. This ice and water can spray around the engine bay and if there is any electrics that are around it can cause a short circuit.The easy way to fix this is to identify the air con pump and condenser, then spay WD40 on all the electrical components you can see in the direct area.
WD40 displaces water and will cause no problems with the cars electrics.

How do I fix a problem of engine cutting out when I have air conditioning on and I slow down ?

idle air control valve problem , maybe ! Clogged passage . When you put extra load on the engine , such as turning on the A/C the PCM is suppose to raise the idle RPM . With a up scale scan tool you can see if the PCM is controlling the IAC valve . There are videos on you tube on cleaning The IAC , plus testing !
PCM is the engine computer ,just in case your not familiar with that .

Diagnostic code P030

is there another number in the code
It would appear that the idle speed is not at the recommended idle rpms and the extra load from the ac is stalling the engine

Transit van cutting out

Okay, no codes and cut out and low idle,

I have seen this on many types of cars and trucks, first have the tech clean the throttle body, make sure he uses a good cleaner and tooth brush, open the plate with his fingers and brush carbon build up off throttle body and plate then rinse clean with throttle body cleaner, next check and clean mass air flow sensor ,

What happens is the throttle plate when closed allows a small amount of air to pass, after time carbon build up closes the gap little more causing lower idle at stops or when gas pedal released in turn causes engine stall at times, the mass air flow sensor also can cause a problem when diodes that read air flow get dirty and allows air to enter without computer knowing and causes lean condition,

On 2004 Trailblazer, when air conditioning is turned on car does not idle right almost cuts off. no problem at speed, only idle & slowing down.

I would suspect the clutch on the air conditioning unit, also if the unit is overcharged
from a recent charge this would also bog the engine. At speed it would not be as pronounced.
Hope this helps.

Idling goes up and down

If the air conditioning is on, then the engines idle will increase when the air conditioning compressor cuts in, and slow down again when the a/c compressor cuts out again.
If your model has a heat switch, if this is on, then the engine will idle faster, until the engine temperature reaches about 50 deg C, then as the glow rail switches off, the idle also drops back to normal.
