A/c Problems (loud Squeal

[Pope&Youngseeker]

Went under my truck the other day to take a look at the A/C compressor and see why my A/C would not come on. Found two wire connection one of which I figured was power and the other maybe a low pressure switch?? One had two pin connections the other had 3. Grabbed my meter and checked to see if I was getting voltage at the wire with two pin connections and did not see anything (DC or AC). Gave up and plugged the wires back in. Went into the truck today and tried the A/C and it came on for the first time since I bought the truck back in March. But when the compressor first starts up I hear a loud squeal noise even during A/C operation it will intermittently make the noise. Not sure if it is the compressor, belt, or pully???? Any suggestions? Please Help

 

Thanks

A squeal is normally a belt slipping. Hard to know for sure what the cause is on here.

Probably the tensioner, mine went bad and mine and kept throwing the belt off every now and then.

He said he hears the loud squeel noise when he puts the A/C on, so obviously noise is isloated to compressor. I would think a bad bearing and compressor will eventially fail if not repaired. I remember having A/C compressors squeel on me with other vehicles I've owned in the past and wasn't long before they failed after noise started. Could very well be you need to have it replaced soon. If you have a warranty then there's nothing for you to worry about as far as cost. Those compressors aren't cheap either. I would imagine at least $600 and higher for a compressor. I always ran my A/C for a little bit in the winter in my vehicles as it is good to run it every now and then. They should be run every once in a while even though you don't need to because there are moving parts that could bind up if left dorment over time.

Your statement is very true, but I was trying to say the spring in it was fatigued. But, you're probably smarter than me, because I never use my air conditioner unless the wife rides with me. I like the windows down, myself.

Thats hot down in GA during summer. I think I would have my A/C quite a bit down there!

Very true, I went outside today to start painting my bumper caps and started to sweat. I had to keep my head wiped off so I wouldn't buger up the paint job.

I have family that lives in GA down in the southern part of the state on an island. And at night there is so many insects that hang around the doors and windows cause they are attracted to the lights and if you open up either, they bum rush you into the house. That would drive me crazy! Some insect zapper's would come in very very handy there. I really like the spanish moss in GA, how it hangs off the trees.

compressor is seized, un plug it for now that will put a crapload of drag on the belt. you can get them to drain and re-fill the frion(spelling) sometimes that will work but its a risk cuz that stuff is pricy.

I had a concern about my A/C last year and had it looked out. They determined that their might be a possible leak and when they hooked up the machine that fills the unit with the freon and dye, my compressor took quite a bit of it. They wanted me to come back in a couple weeks so they could inspect for leaks. So I came back at that time and they used their special light and found no evidence of a leak. So I came back 2 weeks later, and still no evidence of a leak. During this entire time, I was never charged for the freon they put in or the dye. Not sure how your local repair shop would handle this, but if all the repair shops performed leaking tests this way..Meaning - Fill A/C compressor back up with freon and dye and do not charge customer until leak is found, then this would be some kind of loop hole where the consumer can get a free refrill of freon.
