Today I did a recharge and it seem to work so the back A/C is blowing cold air then the front air.
The front air getting cold but not too cold. I already change the blend actuator. So I don't know what else that needs to be done. If anyone knows something let me know please. Thank you

Good afternoon,

Can you give me the high and low side reading of the A/C system with the engine running and the A/C on?

I need to see them in order to see if the system is working properly.

How much Freon did you install?

Thanks you for getting back to me.
I installed 20oz Freon into the truck I used the A/C pro can with the hose.
How can I check the reading of the high and low?

You need a set of pressure gauges. You can get a cheap set at harbor freight.

Once you get them, hook them up and watch the readings when you turn on the A/C system. Tell me or take a picture and post it here so I can see the readings.

I may be either low or too much Freon in the system.
