Air conditioner not getting cold

Good morning.

There is a blend door actuator that controls heat and cold commands from the control head. It is a very common failure for this issue.

Before assuming this, the AC system needs to be checked for proper pressure. You need a set of gauges to confirm. You can rent them at a parts store.

The tough part is that the dash has to be removed in order to access the blend door as it is located on top of the heater case.

Warning: On vehicles equipped with airbags, disable the airbag system before attempting any steering wheel, steering column, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in an accidental airbag deployment and possible personal injury.

1. Disconnect and isolate the battery negative cable.
2. Remove A/C housing from vehicle.

REMOVAL

Warning: on vehicles equipped with air-bags, disable the airbag system before attempting any steering wheel, steering column, seat belt tension-er, or instrument panel component diagnosis or service. Disconnect and isolate the battery negative (ground) cable, then wait two minutes for the airbag system capacitor to discharge before performing further diagnosis or service. This is the only sure way to disable the airbag system. Failure to take the proper precautions could result in accidental airbag deployment and possible personal injury.

Note: Before starting this procedure, be certain to turn the steering wheel until the front wheels are in the straight-ahead position.
