About a week ago my heater just decided to stop working. The fan only blows cold air. After doing some research I found that it is a common problem in my 2004 Jeep Grand Cherokee Laredo for the heater blend doors to stop working. I assumed this was the problem and have been searching for the best and least expensive fix (about $80 for new doors)
Shortly after my heater quick working I was driving and my temperature gauge shot up to about 240 degrees and in the red zone. I popped the hood and discovered I was low on coolant.
