Four problems related to blower have been reported for the 2002 Jeep Laredo. The most recently reported issues are listed below.
Visibility: defroster/defogger system:windshield:blower took vehicle in for checkup and told them it was making a noise and we thought something was wrong with the system in 2003. In 2007 the blend door was broke - cost over a thousand dollars to get it fixed.
Heater quit working only blows cold air, will not defrost windshield always fogs and frosts on interior, must stop on hwys to avoid crashes with other cars.
One cool morning my 2002 Jeep grand cherokee limited stopped blowing warm air from passenger side vents. Searching for a possible solution to my problem, I come to the conclusion it might be my blend door actuator that has broken. I am unable to afford the repairs . . . Dealerships are quoting me almost $1300 to fix. I have done nothing to cause this problem. After reading article from many grand cherokee owners, they have had the same problem. This needs to be taken care of soon.
(1)hot/cold air blowing blend door from vents is not working. (2)air circulation button is not working properly. (3)dashboard have a creaking sound coming from its underside when I turn on ventilation. (4)front & rear differential make noises when turning.
