Cool 2001 ranger

I bought my truck back in May. I don't use the air alot, but I noticed when I did that every few seconds there would be a clicking sound. A guy told me that it may be low of freon and that the compressor may be making the clicking noise. The air was plenty cold.

Now that we are getting cooler weather, I have started cranking the truck and using the heat. This same clicking sound can be heard every few seconds. When it makes the sound while driving, it feels like it pulls the power of the motor down somewhat, then it will click again and the full power feels restored.

It goes through this process, clicking on and off. Any suggestions on what is going on, and how to correct it? This is the first vehicle that I've owned that has done this.

Thanks,
Dean

I agree w/ your buddy. Most vehicles run the A/C when in defrost mode to remove moisture from incoming air. The clicking is the clutch on A/C compressor.

Cool clutch on A/C compressor

Is this something that needs fixing, or should I just deal with it for a while?

The cooling and heating work fine. It is a little annoying while driving with the constant clicking on and off.

Any idea how expensive and what is involved with fixing this? Is there an adjustment for the clutch, or does the clutch itself get replaced?

Just trying to figure out which way to go. Any and all suggestions welcome.

its just low on freon you would have to see about finding the leak and refill the system the a/c compressor should cycle on and off and will be more noticable in cool weather but if its cycling on and off that quick it doesnt have much freon in the system suggest seeing a shop for a leak test.

With the heat on? He said it does the clicking even when he has the heat on? (Read the OP 2nd paragraph.)

Henry Ford keeps the A/C on with the heat & defrost to remove the moisture from the air for better defrosting of the windows. The A/C/ will work till almost below freezing to dry out the air. Hope this helps, Roger

You need to get this fixed for the simple reason that it will quickly wear out your compressor clutch which can mean a pretty high bill. Since your air is still working good chances are the system is just a little low, I would suggest having it topped off and some UV dye added which will probably last you for quite a while....when it starts clicking again take it back to the shop or look over the engine compartment with a UV light and some of those groovy yellow glasses and you should be able to locate where the leak is coming from. Could be something as simple as a fitting....which would be a cheap fix compared to a new compressor clutch or, worst case scenario, a whole new A/C compressor.

I had a similar probelm and we thought it was low on freon, it turned out being the low pressure cut off switch was bad ,check your freon or have someone do it then if your system is fully charged you can use a paper clip to jump across your low pressure cut off and determine if it is bad ,That low pressure switch keeps you from burning up your compressor when your system is low on freon
