Hey ExtraShaky, where can I find that Goodyear Gatorback online? Do not see it on PartsGeek or RockAuto.
Great, found it at summitracing.com but there are varying lengths. How do I know what length I need for my Jeep Cherokee 98 Sport 4.0 4x4? I hate not knowing anything about this.

I got mine from Amazon. They had the best price on it at that time.
Always be sure to check Amazon for parts. You will often find what you're looking for cheaper than other stores, with free Prime shipping if you're a member.
You can also search on FrugalMechanic.com for the best prices on parts. You need to know the actual manufacturer's part number. The first few results are usually carpart.com, partstrain.com, etc. These are all the same company. Although the prices are good, they can take a long time to ship and may not ship at all if they can't get your part cheap enough to honor the price. You'll see what I mean if you search it a few times and Google the chespest companies before ordering.

Jeep Squeals When Air is Turned On

Thanks for the suggestion. I'm all about numbers and need something more than "a good feel" to be sure. I noticed a post about a more accurate tension gauge, but I'm sure the one you suggested will be better than my inexperienced fingers. I also appreciate your belt suggestion. That is EXACTLY what I was looking for with this thread.
And I wondered all sorts of ways about the compressor. It only happens when I run colder, or when the humidity is up. When at running temp, I have no issues with squealing at all. And the air runs cold.
STILL... last I checked this issue when I replaced the tension pulley, the tension pulley was making all the noise. It's only been a year but could it be the pulley again?
I wanted to say that I am amazed how you Jeep experts took the time to respond to my question/thread, and again, said it before, it's one of the reasons I post questions here. You guys and gals are awesome and I appreciate your time with your replies!!!
No one said anything about my power door lock issues though. I threw that in hoping for a 2 for 1 bonus. It absolutely SUCKS now! It's like a 5-year-old going nuts on the power locks! Only relief I find is banging the control on the passenger side with a socket wrench I keep in the front seat. LMAO. Where can I find factory control units for those front seat panels other than a junk yard?
YOU GUYS ROCK! THANK YOU!!!!
I say Tension Pulley, You say Idler Pulley. TomAYto, Tomato. lol

On the door locks it could be a couple of things. You will most likely need to pull off the door panel and check for frayed wires or loose connections. Both are common issues. If it's not that there are a lot of posts on search about replacing or rehabbing the switches themselves. I bought some salvage units off eBay and solved my trouble, plus found a loose wire which fixed one door. My door with the loose wire would operate the window only if you thumped on the panel. Once I pulled it I found a repair from the prior owner that was done with duct tape. Swapped it for an actual electrical connector and it works like a champ.
I know I have a ground issue somewhere in the dash. Sometimes the dash goes to all zero, and only a firm hit with my fist on the top of the dash fixes it. Sometimes it happens once or twice a week, or it can go months before it happens again. When it happens, the RPM's, speed, everything goes to off, and the airbag light goes on. When I hit it, they come back, and the airbag light goes out after a few seconds. This anger fix cannot be sustain however, as I noticed the check engine light flicker sometimes when I do it.
I really wish I was capable of taking the dash apart and refreshing all the wire and connections. Perhaps if my wife and I take the plunge and buy a new truck or an economy car. Then I can take my time to do it right. The repair shops charge way too much for this sort of thing.
Sorry, I rambled. I could go on all day with annoyances I need to fix. Doesn't matter the troubles, I love her with all my heart! Even when one of her luggage rack skid trim pieces peeled off and repeatedly smacked my rear hatch window while doing 80 on the 202 today. lol

I guess I need a recommendation for a idler pulley. I noticed that a lot of Jeep people have problems with this part, and I want a good one so I don't have to go after installing a new one a year later. Can I get it at O-Reilly?

I have seen posts here about this before, but never had my suite of questions answered, so decided, finally, to start my own thread.
When I turn my air on shortly after starting my Jeep Cherokee 97 Sport 4.0L 4x4, there is a squeal. At idle, the squeal is pulsed, like not that bad. But when I ramp up the RPM's it's really bad. I turn the air off, wait a minute, and turn it on again. It is less pronounced, but sometimes still happens. I rinse and repeat and it finally stops happening.
OK, sure, I suspected the serpentine belt is loose. I did tighten it and it still happens. One of my questions here is what is the rule-of-thumb for making sure your DIY installed new serpentine belt is at the right tension. Someone told me at the shop I go to that if the tension is right, you should only be able to twist the belt 90° with your fingers and no more. I'm at that level I think. Maybe I'm just too weak? lol.
Anyway, what are the other issues I might consider? Is it the compressor? I just had my air done and the shop didn't notice any leaks or issues with the compressor. And the air is good and cold, even in my hot Arizona summer environment.
Could it be the quality of belt I installed? Would a better aftermarket type eliminate this issue?
I'm at my wits-end with this. It's annoying, but I tolerate it because A) I need the air, and B) it's my Jeep and I love her and tolerate the little issues.
I have another issue with the door locks pulsing over and over while I'm driving, but that's another tolerated issue. lol. Had to throw that in.
Any and all ideas would be greatly appreciated. Along with recommendations for new gear/parts, even a better aftermarket serpentine belt.
Thank you guys on the best Jeep forum ever!!!! for your time!

I’m having almost the same problem on my 98 Xj 4.0l every time I turn my heat or ac on I hear a squealing noise coming from the engine bay but after a couple minute of driving it will stop but when I stop at a red light and pull out it begins squealing again

Check belt tension. If you don't know when it was replaced last might as well replace it. Rock Auto carries quality name brand belts. Pick up the Krikit II gauge on Amazon or from a local parts store.
FSM states 180-200 lbs on a new belt. 140-160 on a used belt.
