The contact owns a 2003 Jeep Grand Cherokee. The contact stated that the blower motor failed when he attempted to use the heat and smoke appeared underneath the glove compartment box. There were no warning indicators illuminated on the instrument panel. The vehicle was taken to an independent mechanic where it was diagnosed that the connected plug to the blower motor resistor melted the wires and plastic cap that surround the resistor and needed to be replaced. The vehicle was not repaired. The vehicle was taken to byford Chrysler Dodge Jeep Ram of chickasha (3121 S 4th St, chickasha ok 73018) for diagnostic testing. The dealer stated that the VIN was not included in a recall and advised the contact to call the manufacturer. The manufacturer was not contacted. The approximate failure mileage was 150,000. The VIN was not available.

Passenger side bend door defective passenger side to hot and does not cool visibility: Defroster/defogger system:windshield:blower.

- Harvard, IL, USA

Visibility: Defroster/defogger system:windshield:blower loss of half of the heater control and ability to regulate the temperature. After phone calls to repair shops, I was told to expect the rest of it to stop working if not corrected soon, as this is a 'common" problem with 1999-2004 Grand Cherokee. Estimates were in excess of $1,000. Loosing the ability to regulate the temperature to defrost windows in winter(Wisconsin) and not being able to keep my three year old son warm is a huge problem for me and should be for the manufacturer. A tsb was issued on 01/20/04 for these issues, and it was recommended to replace the respective sub-assembly if any parts were to be replaced. They knew of the issue and nothing was done. Hope to find a dealer to help me with this so we can have heat again. Hoping to not have the same poor service that I received when I had to fix the power steering, tsb's on that, no info from the dealer on that when asked, along with being quoted for the wrong parts.

Visibility: Defroster/defogger system:windshield:blower my heater is blowing cold air on driver's side/passenger takes a long time to blow heat. Ac (air conditioning is also failing) receiving these codes: 52...........................ai (recirc) door travel too large 54...........................left temperature door travel too large the problem with the Jeep Grand Cherokee limited is a design problem. The system uses a stepper motor that detects the extents of movement by hitting a resistance point at the open and close point. The system is designed with a small plastic pin on the door connection pin that breaks over time. When the pin breaks, the resistance point occurs when the door hits the extents of the open and close position. The door is not designed to handle this force and eventually the door itself actually breaks. Please note we are currently in -3 celsius weather in mississauga, Ontario, Canada. I will be taking my 2003 Jeep Grand Cherokee in for warranty service. If this is not covered under warranty I am looking at a bill to fix between $300-$1500 Canadian. After going to dealership with warranty claim will call 1-800# and provide details from dealership visit. This can be considered a safety defect since could affect defrosting of windshield while driving. Also very uncomfortable to drive with no heat (in winter) and no ac (in summer) please respond to my complaint asap. Thank you I have read several posts on the internet that Jeep from 1998-2004 all have the same problem. Update: I have received service for Jeep on January 21, 2008 I have put in a complaint on Jan. 21/08 reference # 17140103 issue was blend door fault. The blender door on left side was melted. Parts replaced: 05012743 housing 24-028-025 05134353 housing 24-028-025 total parts and labor $473.27 please followup with Chrysler why this is a not a recall. Jeep is not drivable in this condition.

Almost immediately after the warranty ran out, the passenger side of the automatic zone control stopped putting out heat, only cold. Then about 5000 miles later the entire vehicle stopped putting out heat altogether. This is a very dangerous safety issue due to the fact that there is no way to keep the windshield clear of ice and fog. This makes the vehicle unusable during half of the year. This is a well known, common problem that should have a recall placed for the repair. There has not been any action taken yet to repair this problem because it is so expensive to have repaired. ($800 to $1500).

I am experiencing the same "door blend" malfunction that thousands of others are experiencing. One day the substandard vent door for the passenger side climate control broke, and since then only cold air blows from those vents as well as the windshield defroster. The defroster worries me the most as without a clear windshield my vision is thus impaired and could potentially lead to a deadly accident. I have spoke to a Jeep dealership who informed me that it is a very common problem and it would cost me upwards of $1,200 to fix. After checking the internet I see thousands of other Jeep owners with the exact same problem, yet no factory recall. Jeep needs to fix this problem for its customers before dangerous or deadly accidents occur!

The passenger side of my Jeep was blowing cold air. I took my Jeep to the dealer and was told that the temp door and fresh air doors were broken. He also stated that this was a common problem with my Jeep. Also, the drivers side heated seat was very hot when it was on the low setting. They found that the heater grid had a short in the circuit. The sum of all repairs was $954.60.

Cold air started to come out of heater vents on driver's side even though heater was set on heat. This happened on a journey in a ice storm. Wind shield could not be cleared and a dangerous level of visibility caused me to stop driving. I was told be a mechanic that the heater blend doors had failed (broken) and that this is a very common problem with the Jeep Grand Cherokee 02-04 model year. This is potentially a disastrous safety issue that Chrysler corporation are fully aware of. A dealer repair is quoted at over $1400!

Visibility:deroster/defogger system:windshield:blower factory defect in the blend door. No heat coming out on the passenger side, only cold air. Have lost visibility of entire passenger side wind shield during winter conditions. Very dangerous, almost got in an accident because I couldn't see since the windshield froze up and I didn't have warm air coming out of the passenger defrost.

My 2003 Jeep Grand Cherokee with electronic dual climate controls and 66,000 miles will only blow cold air. Both blend doors are stuck on full-cold. The fault severely limits my ability to defrost/defog my windshield. According to industry experts I've talked to, the fault is common to all 1999-2004 Jeep Grand Cherokee. The repairs are exorbitant; estimated at $1,600 to $1,800.

2003 Jeep Grand Cherokee limited - no heat on driver's side - passenger side heat is still working. I checked the codes for this problem and it seems to be related to the "blend doors" located in the heating/cooling vehicle ductwork. I also did a great deal of checking via the internet to see if there were other Jeep owners having this same problem. To my surprise, I found that there were a great many other Jeep owners all complaining about the exact same problem. It also appears that this is a very costly repair (I saw where people had paid as much as $1800 to get their heaters working correctly). This is not just a comfort problem (drivers and passengers being too hot or too cold), since it also effects the windshields defogger/defroster ability, which of course, can lead to an actual dangerous driving condition. With so many Jeep owners experiencing this exact same problem, it's clear that this is a major manufacturer defect and should lead to a recall to repair the problem at no charge to the owner.

Extremely cold air began blowing from vents when heat was on. This malfunction prevents the windows from defrosting destroying the visibility from the windshield and driver and passenger windows.

I put the heat on in my 2003 Jeep Grand Cherokee only to find cold air blowing from every passenger side vent (the floor, the dash, & the defrost). I called 2 Jeep dealerships regarding the problem and they both informed me that it is a blend door issue which will cost $1000 to $1400 in order to fix. After searching the internet, I've found that many other people have run into the same exact situation.

Blend door failure, cold air during heating mode.

- Indianapolis, IN, USA

Blend door malfunction. On the passenger side of my Jeep I always have cold, no matter how many times I try to change the temp to get the doors to adjust. Driver side has sporadic problems with the blend doors. Sometimes it will be the temp that I want, and other times it will be the complete opposite. When I asked the Jeep dealer in town, he estimated that it would cost $1400 to fix the problem. I had bought the Jeep from a dealership 4 months prior to this happening. I have done nothing to correct this problem because I refuse to pay out of my own pocket for faulty equipment that was installed by the vehicle manufacturer.

I get cold air on the driver's side and hot air on the passenger side. The dealer said it was the blend door, it's a common problem with Jeep..
