Over time it may become necessary to replace the climate control module. Signs of a faulty climate control module include an inability of the heater or A/C to work or simply maintain a constant temperature. Or you may have the setting set to cold and instead heat is coming out.  In order to remove the climate control module, the front cover must be removed.

Before you do any work on your car it is important that you wear safety glasses and work gloves. If you have to jack up your car, make sure to use jack stands and chock your wheels as well as applying the parking brake. Protect your eyes, hands and body from fluids, dust and debris while working on your vehicle. Never work on your vehicle if you feel the task is beyond your ability. Always disconnect the battery before working on your car.

Using a flathead screwdriver, gently pry off the climate control cover.
