A/C help needed

[Don and Dale Champagne]

Getting cold air from vents but barely feel anair flow.

Blower motor is working with controls speed increases and decreases.

Pulled and cleaned Blower motor that was behind glove box.

Can the evaporator be cleaned without removing?

Thanks in advance for all feedback.

Not really.

Is the airflow correct when in vent and heat modes?

JKP asks a good question.

I am not specifically familiar with the Jeep, but I would look to the heater resistor pack since it’s running, just not fast enough, that could be your problem. My daughter had a Cherokee, can’t remember what year, but it had a resistor failure and there was an upgraded one for it. It should be worth looking into. If it’s easy to get to, take a look at it. If it is bad it will probably be discolored.

Hope this helps.

Yes.

You need to see pictures and study them. Then cut a hole in the box. Use a pump sprayer to clean it. Other people drill a hole and use the expanding coil cleaner. I just used the purple Fabulosa (similar to pine sol and simple green). Only cut the hole on 3 sides and use buytl tape to seal it back up. You can also clean your core at the same time through a different hole, but you will need to lift the driver's side up a ways.

You need to check the blend doors for proper movement.

Pull up the FSM under Resources.
