The vehicle was included in the recalls associated with NHTSA campaign id numbers 06V197000, seats:front assembly:seat heater/cooler, and 09V117000, seats:front assembly:seat heater/cooler. The vehicle was repaired at an authorized dealer for both recalls. After being repaired he noticed that there was still a hole developing in the front drivers seat due to the heated seating feature.

The failure mileage was 49,742 and the current mileage was 150,000. The consumer also stated the driver's exterior mirror also had a problem with the heating element. Also, the vehicle had an evaporated emission leak which caused the vehicle to fail inspection.

Having trouble with ac- had valve replaced, the next day air stopped coming out of the vents. Took back to shop and had to have the blend door replaced. Have researched on-line and this is a very common & expensive problem.

All of a sudden the air conditioner (A/C) di dnot work on the 2003 Jeep gc limited. The A/C worked on the driver's side, but on the passenger's side it kicked out hot air. The error code was #56 and stated that the right temperature door travel was too large. So the whole dashboard has to be taken out, and these doors had to be replaced for over $1000.

  • Automatic transmission
  • miles
There were no events leading up to the failure. I purchased my Jeep in the summer 2003. Everything was working properly. The following summer 2004, the ac went bad and stopped. I had it quoted and repaired. Now, in the first qtr of 2006, the ac does not work again. I had it quoted and the repair cost was estimated at $650. This time, the failure is due to the trap door and face not working.
