1999 Jeep Cherokee Squeal and RPMs and Battery Charge Indic

See my profile. Recent Posts. It really sounds like your A/C clutch is freewheeling like it should when A/C is off.

(Defrost also engages A/C clutch, and may result in same squealing)

It sounds like when A/C Clutch engages A/C COMPRESSOR (A/C ON or DEFROST)The compressor locks up and either, that Pulley can no longer turn or is barely turning.

The engine strain is Horsepower. Trying to pull against.A Dead Pulley

The squealing is your belt, in the "BURNING MODE" thru the DEAD/ DYING pulley, and will soon FAIL, if you continue with current condition. No Belt. If you drove it too long. No water pump circulation. FRIED HEAD(S). STRANDED.$$$ REPAIRS $$$

This could be from TOO MUCH REFRIGERENT or your COMPRESSOR BEARINGS ETC. ARE BAD, or something else (I cannot see it from here!)

If you took it to a REPUTABLE shop, maybe it might have some sort of warranty, especially if its overcharged. You know, by the "NEW GUY". Especially if a Cell Phone was in the equation!

If you took it to JIMBOB---I saw Bob Vila do this once, you might be in trouble.

Defitely NO TAKEY BACK TO JIMBOB, He may have already displayed his know-how. WANT A DOUBLE-DIP?

REPLY?

If you thoroughly checked out my profile, investigated my votes, particularly the NEG one, you will see I am a Member here, like you.

I am no Expert, BUT-BUT-BUT I do know some stuff about "mechanicing" (I do mine, family, and friends) and I am ONLY trying to get you squared away and on the road!

Run "Defrost and Heat" mode (whatever it takes to get Hot air on your windshield) Since I am unfamiliar with your particular rig---see if squealing occurs, giving this factor a Fair Shake.

If it were tensioner, I would think, the problem would be constant.

I stand, UNMOVED, with my 1st "Nelsomatic Diagnosis"----something wrong with Mr. Compressor.

I will try for "BETTER HELP HERE"

Do not reply to this post, or my next post---WAIT for another response from another guy---then If you want to respond to me. Please do.I like replies!

IS THERE ANOTHER DOCTOR--IN THE HOUSE?--NEED SECOND OPINION

Love, Turddog

Check the serpentine belt, and tensioner pulley, after 174,000 both need changing. Belt may be slipping and causing both the squeal, and the low charge indicator light.
