I have recently noticed my ac only blows cold air occasionaly. When the ac does blow cold air it is really cold, but it doesn't always work. Along with this the engine is bogging down and when the engine does this that it when the ac does blow cold air. Now the engine seems like it is misfiring because there are alot of hesitations when driving but only at slower speeds and now the ac does not blow cold air at all.

Hi targa,

Thanks for the donation.

Is the bogging down of the engine only at idling? While driving is it felt much?

What is the idling speed before and after the compressor cuts in, (blowing cold and not)?

The hesistation could be due to lack of engine power caused by a misfiring engine or low idling rpm.

Have you checked the spark plugs and related parts?

If the AC is not blowing cold at all, you need to check if there is enough freon in the system. Check if the compressor engages and stays so when it is turned on.

Thanks for your quick reply,
The engine bogging dow is during driving at any speed. This used to make the ac blow cold air. The ac never comes on at all anymore even when the engine is bogging down. I do not hear the compressor even trying to come on anymore.

Hi targa,

If the compressor felts like it is not working anymore, you need to check if it is lack of freon or an electrical fault that is causing it. When it don't work, the blower would not be able to provide cool air.

Is the Check Light showing?

Hesistaton during slow speeds are usually caused by misfirng spark plugs, check them and the wires, distributor caps and rotor.

Thank you so much for your help. The check engine light is on. Just one more question if I may. Is the electrical fault going to be expensive to have fixed?

Hi targa,

You are welcomed.

That depends on what is the problem.

The CEL only tells you something is wrong, you need to get a scan to find out what is wrong. Cost will depend on the item to be rectified, might just be some disconnected wires or it could be more expensive items.

Get a scan done free at Autozone and come back with the codes if you are not sure how to pregress.
