Hey Guys, will someone please tell me why my a/c makes a scretching noise when I turn it on. It's beyond freakish. Thanks guys!

 

belts loose ...horn please ,...lol...

 

When was the last time freon was added?

 

Ok, I will do the horn first.

 

This would not cause the belt to make a screeching noise. That would only cause it not to cool or it just would in-gauge the AC clutch.
More then likely you belt is lose.

 

Or you need a new compressor bearing.

 

Or the blower motor/resistor is crapping out. If the noise comes from the vents, thats the problem. If it's up front, it could be with the A/C components.

 

from a tighten the belt task to freon, bearings and blower resistor in three post ...no wonder part stores do so well...

 

Well we are just giving out ideas since we haven't heard back from them. It could be a number of things.

 

i know but it just went down hill quick was my point few more post she woulda need new motor..and them is a she singular...lol

 

Ding ding ding ding!

 

I'd verify belt first. A worn, glazed or especially a loose belt will make the screeching noise upon engaging the compressor.

Perform a close inspection. Any shiny (glazing) spots is not good. If the belt has over 60k on it, just replace it with a Goodyear Gatorback belt; the best replacement belt in my opinion.

If belt is newer and passes inspection, be darn sure that it is tensioned properly. I use the Krikit II tension gauge. The belt on the 4.0 needs to be pretty darn tight to keep quiet.

 

Thanks Free. Big G! You're right, one step at a time. I'm a NYC slicker, always moving. I live in the south now I must slow down!

 

Mine made the sound of a dying bird coming from under the glove compartment the other day but now seems to have stopped... what's that about lol

 

Sounds like your blower motor.
