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?
View 5 RepliesWhen I turn on the air conditioning, the driver's side works well, but the passenger's side vents blow warm air. What could this mean and could I fix it from home?
View 1 Replies01 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>?

It returns to the proper setting when you leave off the gas feed.One can hear the blend doors changing. I am mystified, because I thought that vacuum operated blend doors went out decades ago.
View 17 RepliesI can't seem to get the engine temp to middle range on the marker, but yet my heater blows "to me" hot air. Even while sitting in idle for extended amounts of time I cannot get it to "operating" temperature. I would think if my thermostat was stuck open my heater would blow either cold or slightly warm air. I have the 5.4L engine with knn air filter and no cats.
View 14 RepliesMy 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.
View 2 RepliesMy '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.
View 16 RepliesI 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.
View 2 RepliesI have a 2006 f250 and the heater will blow cold air unless you are driving in like highway conditions. If you stop or drive slow it blows cold air only. What is causing this???
View 3 RepliesI have a 2005 Jeep Grand Cherokee Laredo that won't quite start as the temp outside begins to drop into the 70's. It started doing this last winter and is happening again this fall. It sounds like it wants to start but just doesn't get that final ummmmph to start. After several tries and several minutes it will start but how annoying is that! Again this doesn't happen in warm weather only mild and colder. What is the cause of this problem and what to do about it?
View 2 RepliesI have a 94 ford Taurus all of a sudden my ac doesn't blow cold and my heat doesn't blow hot. Also every now and again I hear a sound like an alarm clock coming from passenger side??
View 3 RepliesMy Jeep sounds like it is in low gear and engine sounds like its turning 4000rpm but only when cold. This is so noticeable that dogs stare and pedestrians run for cover. Once the engine and drivetrain warm up a little, all is normal. The reality is that the engine is only turning 2500rpm and it is shifting, but the tranny doesn't feel like its grabbing very well. After just a few minutes driving, all is well and there is plenty of power. Fluids are all topped off and fresh.Is it time to warm this baby up and drive it to the nearest car lot?

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.
I have a 1998 Gr Cherokee with an automatic tranny. It is slow to shift when cold and the overdrive shifting works reasonably well but I have been told by a reputable mechanic that the tranny needs a new tranny filter at over $1000. My latest check of the tranny fluid and the level and quality indicates both are good. Should I replace the tranny filter?
Also, for the same above vehicle, when I put the vehicle into a moderately hard turn (right and left), the front wheels audibly click and you can feel the click vibration in the steering wheel when happening.
I have owned my 2008 Rx 400 h for just over two months now and at the risk of sounding dense, am I right in assuming that when you are coasting along without the engine running, the heater will start to blow cold air? Everything works fine until you lift your foot off the pedal. This is my first Lexus/Toyota and hybrid so I'm not totally au fait with how it should be working.
View 2 RepliesCannot figure out how to get the heated air to flow through the back via the rear vents. All I get is outside air. I cannot find anything about it in the manual. The dealer has no clue but is trying to find something on it. New 2009 Santa Fe Limited.
View 11 RepliesSo the heater on my 2001 f150 will only blow through cold air. I thought that I may have a heater core clog so I back flushed it with water until it was coming through clean and unrestricted but that didn't solve the problem.
Now, some things to note are a potential coolant leak. I can't seem to find one but I filled up the antifreeze about two months ago and when I checked it the other day it was more or less empty. I've filled it up again and I will monitor it for the next couple of days.
Another thing to mention is that no matter what setting I have the heater on (ie 'panel' or 'defrost') I get cold air blowing at the passenger side's feet. Is this indicative of a hose leak or something?
Also worth noting is that the intake hose to the heater core gets hot after driving but the outtake stays cool. This is why I originally thought I had a core clog.
Should I be checking my blend door? If so how to I access it?
I took my 200000 mile Prius to a garage that is highly recommended and the mechanic stated that I need a new evaporator and expansion valve. He tested the car for a day. There was no time to do the fix so I arranged for a dealership that I trust to do the job. When they were ready to do the work, they detected no leak in the evaporator, but said that the compressor, expansion valve, and AC line needed replacement. (They showed me the leak in the compressor with special glasses.) After I called the first mechanic with the new info, he said that he could detect a leak nowhere, but, in the evaporator, and, at the expansion valve area. I am now stymied as to what I should do.
View 7 RepliesPush A/C button is always on green. The (air speed) 01234 button is also always on green. the Push button turns on and off orange whenever I click it.
Anyways, the AC doesn't blow any hot air... always just cold. I've adjusted the dial to red and have left it there for a long time... no hot air. Any trouble shooting I can do?

Problem 1: Now that is is finally getting below freezing and I am having to use my heat, and I have noticed that it will all of a sudden blow ice cold air. It does not matter if I am idle / accelerating / decelerating. I must provide a disclaimer... I have not had to use the heat in the car since I purchased it Certified Used from the dealer in South Florida. After moving back to where it actually gets cold I find this issue. I had my trusty mechanic look at it and he flushed the heater core. That is problem 1.
Problem 2: For about 6 months now my car has been doing this odd shaking routine. It happens probably every time I am out driving. When it starts to shake, I can prevent it from dying by revving the engine. It does not matter if I have just started the car, am sitting at idle or if I am driving down the road. No check engine light or malfunction indicator light has come on the entire time. It feels like the car just runs hard, not nice and smooth like it used to. I have brought my car in to the trusty mechanic three times now and he can not find any problems. I did notice this morning that while sitting idle at the stop light, my car had its little epileptic shake and then stopped and the RPM's dropped to 500.
Later when I arrived at my destination, while sitting at idle before getting out of the car, the RPM's were at 2000. I have routinely put in fuel injector cleaner additive when I fill up with gas... maybe once a month. I usually fill up with regular gas, but will occasionally fill up with premium. This whole situation is blowing my mind!
