Defogger Heater problems of the 2000 Jeep Grand Cherokee

My 2000 Jeep Grand Cherokee with 90,000 miles has had problems with defrosting and heating for the past year. When it is cold or rainy the windshield will not clear not matter what settings I use. I get snow and ice accumulating on my foggy windshield and I am forced to pull over in dangers conditions and scrap my windows. Recently my heat has stopped working on the drivers side and I looked for information online and found numerous forums with thousands of people having the same problems with their Jeep Grand Cherokees. People have complained for years to the dealership and daimler Chrysler only to be told it was a comfort issue not a safety issue. It is s serious safety issue and I feel this needs to be looked into before someone does get hurt or worse. They are aware of the problem and the dealerships are willing to charge thousands of dollars to 'fix' problems but it should be recalled because they never fix the problem and customers are taking unnecessary risks to drive their SUV's (sports utility vehicles, ironically) without heat, defrost and/or cooling. Please take this complaint seriously and look and see how many other similar complaints you have gotten on the same issues with these cars. I can not afford to buy a new car and I do not want to out myself and my family as well as others at risk because one company is not responsible enough to fix such a blatant safety issue. Thank you.

Ventilation system is blowing cold air even with the heat on.

Air conditioner (a/c) will put out heat when on full cold and neat will put out cold when on heat mode. Air will not blow out vents or defrost but blower motor is working . Started acting up last year and still does it.

Heat hasn't worked on passenger side of vehicle for 2 years. Asked dealer about it and they want over $1000 to repair. Just replaced radiator and now heat doesn't work on driver side. If Jeep actually checked customer complaint website they know that this problem is rampant around the country and they should recall the vehicle and pay to have this problem fixed. I purchased this vehicle used in 2003. Heat stopped working on passenger side by September and I purchased it in July.

The contact owns a 2000 Jeep Grand Cherokee. The heat/defrost function failed in the vehicle. During the winter, the contact must remain cold in the vehicle and the windows become foggy instead of defrosting. The vehicle has been to the dealer twice and they stated that there was possibly a condenser leak in the heater, which caused the control lever for the heating unit to deteriorate. The contact stated that the repair was too expensive. He has found several complaints regarding this failure with the same model; therefore, he believes that the manufacturer should issue a recall. A relay shorted out due to a failure with the heating mechanism and the entire vehicle filled with smoke. There were no injuries. The vehicle has not yet been repaired. The VIN was unknown. The failure mileage was 60,000 and current mileage was 90,000.

My 2000 Jeep Grand Cherokee has had a heater problem. It gets so hot that it can burn my fingers. Then all of a sudden on the passenger side the heat doesn't work it only blows cold air through the vent and on the floor. Also in the trasnmission when you come to a stop you can sometimes feel a loud thump like someone just rear ended you. It happens about 3-4 times a week.
