A/C not working properly?

When you say it is very weak, that makes me think the blower motor isn't working properly. Is that the case? As far as the A/C is not working, do you notice that the A/C clutch on the compressor isn't engaging? You would hear a clicking sound when it engages. Also, have you checked the charge in the system? It could be low.

Take a look at the link below and let me know:

Also, make sure the condenser in front of the radiator (which looks like a smaller radiator) isn't dirty or clogged with debris. If it is, spray it with a garden hose to clean it.

Let me know.

Hi,

If the compressor is engaging, it should be cold unless the system needs to be charged, there is a blend air door not working correctly, or there is an AC component not functioning.

Since the condenser fan under the hood turns on, that tells me the system is operating. So, is the problem air flow, temperature, or something different?

Let me know. Also, hang in there. We'll get it figured out. I just need to have a better understanding. My biggest question is if the blower motor in the vehicle is not working. Also, the airflow directions and temperature controls operate using engine vacuum. There is a chance we have little or no vacuum to the system.

You know, the more I think about it, the more I suspect we have a vacuum issue. I attached a pic below showing the vacuum schematic. At the bottom of the pic is a legend. Anything listed as Mode deals with airflow direction. Do me a favor. Start the engine and listen to see if you hear a hissing sound under the dash near the controller.

Let me know.

Take care,

Joe

Hi,

The compressor clutch should cycle on and off. However, it shouldn't do it too quickly. How fast was it happening?

Let me know.
