Trying to locate the orfice for the air conditioner has front and rear air need to change it built too much pressure on high pressure hose believe its plugged up and need to change also will I need to run somthing through the line to clean it out. You might ask how I know that it built up too much pressure on the high end well it blew up the high
pressue line.

if your high side hose blew there are a couple of reasons that could happen. One is your high pressure got too high. That can happen it the system is overcharged, the orifice is plugged up, or the fan is not coming on...

another thing that can cause the high side hose to blow is if it was rubbing against something that caused a weak spot in the hose. That could cause it to blow without having excessive high pressure.

if you have front and rear air you should have two orifice tubes. the orifice tube should be between the condenser and evaporator. Look at the closest connection to the evaporator

that may be small pieces of the compressor sealing components being pushed through the system. there isn't anything you can do about it but just be aware that your compressor is getting worn.
