It is really simple if you buy the $71 replacement actuator sub-assembly from Jeep. I'd rate it a 1.5 wrench out of 5 on the difficulty scale!

The question you ask is too involved for a proper answer. You need to go to a car parts store, and get a repair manual for your car. They cost about $16.00 Or, go to a Public Library.

The lock actuator is part of the latch. You have to replace the entire latch.

Answer 2

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 beyond 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 maintain 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).

The most common problem with heat on these cars is a broken blend door. The dealership will want a fortune to repair it but there is a do it yourself alternative kit out there. Check them out on Google and ebay and go to the site for full diagnosis and info.

Check at your local convenience store for a coffee counter.
