Hello, everyone

This is my first post on this forum.
I wanted to know where is the low pressure port where I can add more 134a refrigerant to the AC?

My is Dodge Neon 2005 SE (US model, left hand drive).
There is a high pressure port and valve cover for it. At least, that is what I thought, because it's on the line where it runs from the condenser to expansion valve into the firewall (this line supposed to be the high pressure line).

Now, for the low pressure port. I couldn't find it anywhere on the low pressure line (or the suction line). It's not on the accumulator either, I only see a small electronic unit (low pressure switch) on this.

It's easy to find those ports on other cars, but this car is weird.
Can anyone helps?

thanks

 

I even looked in the manual parts, pdf file: there is no low pressure service port found.
I started to think, this car model doesn't has one.
So, I might have to find the part and install it by myself? or I take my car to a mechanic.
This is bad, because other cars have this refrigerant service port and it's easy to find.

but, if anyone know where this port is, I'm still looking for this answer.
I will login later to check this thread.

Many thanks.

 

anyways the low side should be between the windshield washer fluid cap and the motor mount, that is what my chilton is showing.

 

Thanks, Chronoboy
I know it's there on 1995-1999 dodge neon and maybe on 2000 -2002, too
but on my 2005, it's not there. Only the high pressure port.

I uploaded a picture.
The one I circled it in blue could be it. It look like a larger cap in this picture.
but on my dodge neon, it has an electrical wire and connector came out on top of it (they call it low pressure switch).

so, I'm not sure where to

 

ok,
I read on other sites and found another way to add more refrigerant to the AC system.
It's not safe and it's a bad habit so I will not post it on here and recommend it to other people.
