The most common cause of your symptoms is blend-door failure. This is a design flaw created by Chrysler engineers. Basically what happens is that every 20 times the vehicle is started, the A/C system software tells the blend doors to recalibrate to ensure that the airflow is as accurate as possible. The problem is that the stop point is made of cheap plastic. The stop point connected to the actuator breaks. Shortly thereafter, the blend doors break because they cannot withstand the pressure of the actuator pushing them beyont their limits after the stop point has been broken. Passenger side is typically affected first, followed by the driver side. If the doors fall with gravity into the down position, you will maintian A/C. If you hit a bump on the road and they fall into a mixed position, you will have neutral temperature. Either way, no heat is a symptom because that is the up position for Jeep Grand Cherokees (99-2004).
I have tried this product, the Blen-Dor repair kit which will replace the plastic drive connector piece and the plastic blend doors with solid aircraft quality aluminum parts. Aluminum was chosen because it will be close to the weight of the original parts. The blend door shaft is a ½" solid piece of aluminum rod machined to fit. The two doors are aluminum sheet stock tig welded onto the door axle shaft with a foam covering applied to both sides of the door panels, all to make a one piece assembly. The second piece is the drive connector it is a ½" solid piece of aluminum rod with steel pins. The drive connector is machined to fit the actuator motor and to fit onto the end of blend door axle shaft assembly.
