So I took a pressure test on the low and it read 80 its in the red. I cant measure the high cause its to big for the tool I got. I only used about half a 22 oz. can of r134a and that is it. I dont think I pulled a vaccum line and Im not to sure what your talk about dirt from the reciever plugging up, got me lost there. I thank you guys fro your help. If only I could get this thing working.

 

I dont believe I pulled a vaccum line and as far as the expansion nozzle is that located on tht engine bay side of the fire wall or the compartment? Is there a way to check to see if its clogged or do I have to have all the freon taken out to test it?

 

Inside the evaporator, or just where the high-pressure line enters the evaporator. So the orifice/nozzle/whatever is buried in the dashboard.

 

You are confused about what I am talking about.

There can be no air in the system when you try to charge it. As soon as your line broke in your accident, air entered into the system.

You need to evacuate all of the air from the system by using a vacuum pump. I did this by hooking a vacuum pump through the manifold that I bought. You may be able to rent a vacuum pump.

You pull vacuum for a hour, then close the system by shutting off the manifold. If the vacuum holds for a period of time (say an hour), then the system is air tight.

By the way, what tool did you rent?

 

So am I going to have to pull the whole thing out of the car? Am I going to need to take it to a shop to have the freon taken out? I mean can I check it without having to over haul the whole system?

 

You do not have to remove anything out of the car.

I hate to seem rude, but I don't think that you can handle repairing the a/c system on your car.

The a/c system generates high pressure when working properly. For safety reasons, I think that you should probably take your car to an a/c shop and tell them to evacuate and recharge the a/c system.

 

Well I didnt get that last post you sent me about the vacuum pump. Yeah, I understand now. If I rent the vacuum pump do I have to remove the freon before I use it?

Im new to the area and I just wanted to try and get it fixed without having to go to some random shop and being charged out the ***.
