Jeep - Grandcherokee :: 2001 - Overheating / Temp Drops When Turn On AC Or Heater
Apr 11, 2014
My '01 Grand Cherokee Limited is overheating. I have changed the thermostat and ran a leak test. I am not having a leak. The temp drops when I turn on the A/C or heater. I went back to the shop that changed the thermostat and leak test. They said it was the fan control and I have to go to the dealer to reflash the program for the fan control. I made the mistake of asking the dealer to reflash, instead of having them check on the overheating problem. I'm planning on going back to the dealer to have them diagnose the issue.

I inherited a 2008 Jeep Grand Cherokee from my late father and it seems like whenever the temperature overnight drops below a certain level, in the morning the low tire pressure light pops on. I never encountered this problem with any other car I owned, is this something inherent to SUV's with all wheel drive?

I have a 95' Grand Cherokee, V8 5.2L. Recently, it started overheating and was diagnosed as a head gasket issue at a shop. I ended up replacing the head gasket, thermostat, and water pump. (The radiator, top radiator hose, and radiator cap were replaced within the last year as well.) Despite the repairs, the coolant in the reservoir does not move. The Jeep overheats and there is a squealing noise coming from what may be the water pump. There is also a slight leakage of coolant near the water pump bypass hose, but does not seem to be coming from the hose itself. What else am I missing?

01 Jeep Grand Cherokee. I just changed the water pump and the thermostat on the Jeep but the last two days when I drove it to work, the heater was blowing cold air and the engine was getting hot, almost to the red. What do you think that I should look into about getting the problem fixed>?

My 99 grand cherokee's heater is broken - fan blows but only cold air. I've had two mechanics tell me its probably the blend doors and will be quite expensive to repair because it requires removal of dashboard. Looking for after market repair kit which allows for a DIY fix going through the glove box? Is this a good bet to try?

My heater/AC blower quit working. Does not work with either heat or AC. I suspect a blown fuse but cannot find one for the blower.

The ambient (outside) temperature sensor on my 04 jeep grand cherokee is now stuck in the open position (it reads -40 constantly) after having body work done to it. Could this be a fuse, loose wires, or is the senor broken? Also could this have been damaged by the body shop?

I have a 2003 Jeep Grand Cherokee with about 240000 miles on the clock. Words cannot describe how impressed I am by this car. However, yesterday I noticed that the selector switch where one chooses to direct the air output has failed me. It seems to be stuck in the windshield defrost setting, unable to redirect the airflow to anywhere else. I am however still able to control the temperature as well as A/C settings. The switch felt strangely 'limp' almost as though it is no longer connected to whatever engineering or witchcraft it is attached to behind the control panel. What are your thoughts on this? Could it be as simple as some mechanical linkage that has snapped off? Just to recap: blower motor, heat and A/C are not affected by this.

1998 f150 4.6 4x4 auto 180k .... Runs 100% other than a strange and inconsistent overheating issue.
On cold startup truck will warm up. Then the temp gauge drops to practically 0. After 15-20 seconds gauge shoots up to max and then falls back to normal after 15-20 seconds. Then it'll go back to driving normally. At some point it pukes.

I have a 1996 Jeep Grand Cherokee with 152k miles on it. Recently replaced battery. All of sudden yesterday, engine will turn over and try to run but sputters out and dies after about 30 seconds. Cannot maintain idle on it, and none of the gauges rise when you turn on the ignition, so that you cannot see the RPMs and the gas gauge reads empty even though I filled it up two days ago. Tried to start it today and saw the same problem but with no sputtering, engine dies within seconds now.

I have a 2006 Jeep Liberty 3.7L that has a temperature gauge on the dash that reads an overheat when driving. The oil looks normal, there is no white smoke, no bubbling from reservoir. I have replaced the following:
Radiator
Thermostat
Water Pump
Coolant Temperature Sensor
Coolant Reservoir Tank
I am not leaking any coolant and the reservoir level has been fine. I have let the vehicle idle for 20+minutes, with no overheat. When I drive it around, the temperature gauge will read an overheat. When I stop the car and pop the hood, the engine is not overheated and both rubber hoses to/from radiator are flowing the coolant. The only thing that will bring the gauge down is turning on the heater full blast. Could this be the gauge itself being bad? Could it be a short in a wire somewhere? I had thought maybe a head gasket, but have no symptoms of a head gasket.

This problem started out about a month and a half ago. It started missing slightly. Then I noticed my gas was going down very fast. So I started watching it, A five mile trip used a eighth tank of gas. It keeps getting worse. My husband popped the hood and was looking to see if he could spot anything.( Couldn't smell any gas) He noticed the purge control solenoid wasn't making the noise it normally does. He took it off, cleaned it and put it back on and it started working again. ( NO CHECK ENGINE LIGHT WAS ON AT ANY TIME ) It did it again.
So we called the dealer, made an appointment, took it in, The dealer service guy said he Scanned for codes PO443 Performed Diagnosis Found EVAP PURGE SOLENOID Sticking Open. He said everything else checked out good. He ordered the part, called said it was in, went back, installed it. Amazingly IT"S STILL NOT WORKING. Now, I Do Not TRUST the dealership. It Stalls and misses and spits and sputters when it is in park and you give it the gas. There's times when I am at a parking lot waiting to get out and I start to pull out it trys to die on me.

I have a 2001 Grand Cherokee 4.0L with 215xxx miles. It just started stalling coming up to a stop, but then it starts right up no problem. Engine idles a little rough and the gas mileage has gone down somewhat. The CEL came on a while ago, and the auto shop checked the computer code and said it was the neutral safety switch. I brought this up with a friend who had the same problem and he rebuilt his and said it was easy. So I was going to attempt it, but I can't find the darn thing. @ questions:
1)where is it? and
2)could the NSS be causing the stalling?

My daughter's Jeep check engine light is on. Trying to get the car inspected so cannot be ignored. I think the code wasP0422, indicating it needed a new gas cap. We bought a new gas cap, cleared the code and it went away for a few days but before she could get it inspected, the light came on again. I saw similar problems suggestions were to get a better gas cap (we got one at autozone), or it could be something like a pump problem. We haven't taken to a dealer - it's a 2001

The sound is random, inside the cabin, probably comes from in front of the driver. Lasts for a few seconds but goes on repeatedly. I found that when I apply the brakes, even a gently tap, the sound goes away, but will return.

I have a V6 Automatic 2001 Jeep Grand Cherokee with 94k miles on it. For the last two years my transmission has been slipping only when I make left turns. I have tried changing fluid and filters. The problem hasn't gotten worse but it is pretty dangerous as I cannot accelerate when I make a left turn. I was wondering if there is anything that could be causing this problem.

Two things are going on with my car. First, when I drive at freeway speeds and turn on the heater, the car temperature drops and then I hear the sound of a tea kettle going off. Second, I hear an off and on sound coming from under the hood on the passenger side. It sounds like metal scratching on metal or like a soft whistle sound. 1997 Honda Accord LX

Gauge/Sensor Problem ??? Great oil pressure on start up (40-60 PSI) but as car heats up, gauge SAYS pressure is dropping below 20 PSI. Dip stick says plenty of oil and filter is brand new. No knocking from valves either.

i have a 01 b5 GLX 2.8L with the automatic climate control, well on occasion my temp will be reading fine than all the sudden drop to -36 degrees in 4 degree increments. when this happens my ac thinks its cold outside so it stops blowing cold air and blows hot air. i have to let the car sit with the ignition off for 15 min before it will reset. Is it my temp sensor that's bad and if so where is it located at?

My 2001 Ranger V6 with 160.000 miles runs like a Swiss watch. After warming up slightly it idles at the typical 750 RPM. I can pull out of the garage, park in the yard, shift from D or R into P and the idle holds at 750 RPM until I turn the engine off.
But, If I've driven to warm the engine to normal run temp and go through the same D or R and into P, the RPM drops to nearly Zero and sometimes the engine stops.
This has happened in the past so I take out the MAF, squirt it good with MAF cleaner, put it back in and everything is hunky-doory. But not this time. What am I missing??
