CHEVROLET TAHOE AIR CONDITIONER ORIFICE TUBE

The Ac Wasn't Working. I Have Replaced The Compressor And The Orifice Tube And Recharged It And It Is Still Blowing Cold Air.

I Have Priced The Compressor, Dryer, Orifice Tube, O-ring And Gasket Kit. I Do Not Have The Machine To Pull A Vacuum On The Vehicle....

Orifice Tube Will Not Go Into Pipe. Is There A Tool For Replacing Orifice Tube?
