Jeep - Cherokee :: 2000 - High Pitched Whistling Noise In Cool / Cold Weather

My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...

-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.

However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.

When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.

Jeep - Cherokee :: Air Conditioner Does Not Always Blow Cold

I have a 1999 Jeep Cherokee and the air conditioner is giving me some problems. The issue is that at random times, it stops cooling, and just blows hot air. Sometimes I can drive all day, and it's fine. Other times, it only blows cold for a few minutes, before the air gets warm.

I've started checking under the hood when this happens, and the compressor is not engaged. I noticed a couple of times that the hoses were frosted over (not every time when the compressor was out). I have found that when the air starts blowing cold, I can turn on the heater for a few minutes, and then when I turn the A/C back on, it will blow cold air again. However, often times the cold air will only last around 10 minutes before it blows warm again. Plus, there are a couple of instances where the heater trick didn't really work.

Jeep - Cherokee :: 2000 Always Starts On Second Or Third Go

I live on a boat access only island, so desperate. This jeep has over 230,000 km on it. Runs well, but this year started this thing where it won't start first time crank, but always starts second or third go. Bought new battery last year, so doesn't seem to be that kind of issue.

Jeep - Engines - Cherokee :: Idle Whistle When Engine Is Cold

For three years now my 2001 Jeep Grand Cherokee Laredo will whistle. Usually when the engine is cold. When the vehicle is idling in the driveway or at stoplights, whenever I take my foot off the accelerator it will whistle too. The only time it won't whistle is when the gas pedal is being pressed. I've had it to a number of different shops to be serviced but once the car is inside or the engine is warmed it will never whistle for the mechanic looking at the vehicle. I've been told that it could be related to the IAC motor.

Jeep - Cherokee :: 1996 - AC System Only Blowing Cold Air Out Of Defroster Vents

My 1996 Jeep Cherokee A/C system pushes cold air but out of the defroster vents not the A/C vents. Why this is happening? I suspect it is the slide switches for the A/C system but I am not sure and do not want to take the dash apart before I have some confirmation. I have checked the vacuum hoses with the heater/A/C system and they seem fine.

Jeep - Cherokee :: 2000 Would Not Start / Turn Over Then Die

This past week when I went to leave work my jeep would not start. It would turn over once, and then die....but if I kept my foot on the gas and kept the RPM's up it stayed running. So, I drove it home with one foot on the gas and one on the brake so it wouldn't stall out on the road. The next 2 days the same thing happened when I went to leave work. It starts fine the rest of the time, even first thing in the morning when it's cold..

Jeep - Cherokee :: 2000 - How To Replace Air Compressor

Last fall I had my mechanic replace the broken air compressor on my 2000 Jeep Cherokee with a by pass. I didn't have money to replace it at the time and I still don't. I want to pick up one at a junk yard. How to do this? Where and how to learn more about maintaining and repairing my vehicle.

Jeep - Cherokee :: 1989 - Idling Too High / 2000 RPM At 35 Mph

I have an '89 Jeep Cherokee and it idles way to high. In park it idles at from 1500-3000 after being warmed up. In drive it idles at 1300-1500. It idles at 2000 at 35 mph. We've replaced the O2 censor, the throttle positioning censor, the coolant temperature sensor, and a few other parts. None of this worked.

Jeep - Cherokee :: 1998 - Intermittent Cold Starting / Carburetor System With Choke Sticking

I have a 98 Grand Cherokee (V-8) with 127K on it, that sometimes during cold starts acts like an old carburetor system with the choke sticking. It floods, chokes, it sputters, and you have to maintain an RPM of about 2000 to keep it running and get it to snap out of it. A local shop did a tune up on it before this problem started to happen intermittently, aside from this, it seems to run well. I took it back to the shop and they did several diagnostic tests and even got it to do it for them while they had it.

I told them that it seemed like if we released the key from the start position as soon as it began to fire, the problem would happen, if we held it I the start for a bit longer we could usually avoid it. They returned it to me saying that "Yup, if you hold the start position longer it won't happen, and by the way here is a bill for $103." With the recent below zero temps, it's getting worse, almost unavoidable. My wife says it uses a lot of fuel when this is happening but we have not actually tracked the mileage. Other than this it's a great car but I'm ready to drive it off a high mountain cliff.

Jeep - Cherokee :: 2000 - At Start Up Stuttering / Alternator Or Starter Won't Working?

I have a 2000 Jeep Cherokee 4.0L with about 180,000 miles on it. I'm currently in the middle of a road trip, and today my car's been stuttering as I've started it up. After the car sits idle for a while, it stutters as I turn the key ("chug-chug-chug-chug-chu-chu-chu-chu-fail" is about how it goes). When I take the keys out and put them in again for another shot, it manages to start on the second or third try.

It runs OK once the engine gets going, and after I've been driving for a while I can turn it off and on again, without any problem. My main questions are: (1) Is this likely an issue with the starter, alternator, or something completely different? and (2) just how serious is it? If I can get the car running can I make it another ~1500 miles, or should I try to find a dealership before making it back home?

Jeep - Cherokee :: 2000 - Bucks / Rumbles And Misfires With No Power From Motor

Brooklyn mechanic says "every Jeep Cherokee 2000 6 cyl. 4x4 has this problem--number 3 cylinder mis-fires because it can get too hot". When I return from the country to the city, unload Jeep at the apartment, then, after about 15 minutes, re-start Jeep, it bucks and rumbles and misfires with no power from motor. I pump the gas pedal, and after about a minute it settles down.

Country mechanic has done smoke tests, looked all over for any compression leak, replaced gas cap, put insulation tape over #3 cylinder, and reported that this problem is in the "data bank" of Cherokee problems, where ever that data bank is. The question is, can one live with this problem, or will it cause more problems? Why does the motor settle down after pumping the gas pedal for about a minute? I've had the starter coil replaced recently, as I was told it can get fried from too much mis-firing.

Jeep - Cherokee :: 2000 - A/C Blowing Warm Air - Leak At Evaporator Coil?

My wife's 2000 Jeep Cherokee has a failing A/C system. Last year it was blowing warm air in the middle of the summer so I took it to a local mechanic who recharged the freon and it was fine through the rest of the summer. This year it is blowing warm again so we took it in for another recharge and it only lasted a few days. The mechanic said there is a leak at the evaporator coil(?) He said the entire dash needs to be removed to repair and it would run about $1000 to fix. This seems a bit steep. Any thoughts or experience with this issue?

Jeep - Cherokee :: 2000 - Thumping Noise While Accelerate From Dead Stop?

Jeep 2000 Cherokee

So I have this thumping noise, almost sounds like something is loose.The noise occurs for a few seconds when I accelerate from a dead stop and then goes away, it returns when I slow down and almost come to a complete stop.The noise also goes away when I put her into 4wd.The thump/rattle sounds like it is coming from the center counsel area and directly under the floor board in the driver seat.My car changes gears smoothly up and down while driving.

I was told it might be a transfer case problem and that it might need to be rebuilt, which makes me worry.
