One problem related to air conditioner has been reported for the 2009 Jeep Wrangler. The most recently reported issues are listed below.
The heater worked great for 3 years, then it just broke 1 part at a time, now it blows antifreeze out the ducts and no heat at all, all the blend motors are broke all the flappers are broke the housing is warped the switch is broke, there is no heat at all it takes 3 days for someone with experience to fix it and the dealerships don't improve it they just replace parts with the same defective parts, this is a shame they wont redesign this heater or the parts and it will need a 2,000$ repair every 3 years, ps. The air conditioning is totally gone too,.
