ok i just got the jeep the ac pump is charged fully and at pressure and running, so first is my ac control deck says ER on it when i start up, it will blow fully but wont get cold and i dont hear the trap moving at all, is there a way to check the board of my ac control to see if its working or not

 

I had a similar issue and mine also said ER but mine wouldn't really blow any air, so I checked the fuse and it was blown so popped a new one in there and now it works like a charm

 

Does the heater work?

 

yes the heat works, and wich fuse is it the ac fuse

 

If you look in your fuse box the one that's inside the engine bay, pop the box open and under the lid, there is a diagram with every fuse and what they do, look for the ac compressor fuse

 

so it was the ac fuse or a diff fuse

 

All swell that ends well
