Hi folks,

I have noticed of late my car is leaking water not a lot but the temp is starting to rise a bit still under half though.

Tonight I noticed after a short drive my air con line had frozen up under the hood.

Can anyone tell me what the problem is and how to fix it?

It would help if you told us which line is freezing and where.

I'm guessing the line that runs along the passenger fender ?

My bad! Yes you are correct its the line that runs along the passenger side fender near the airbox.
Any hints or tips would be appreciated.

So it's most likely getting frosty near where the pipes join just up toward the firewall from the airbox - about halfway along the engine bay. The freezing will go along the pipe toward the firewall.

Near that junction where it looks like the round pipe has a hexagonal crimping, the orifice tube sits inside. It's a gauze filter which regulates liquid refrigerant flow into the evaporator inside the heaterbox. Rubbish in the system blocks them and restricts flow.

So the A/C needs to be evacuated, orifice tube replaced, and regassed. Good idea to replace the accumulator during this as well - the rubbish is coming from somewhere - might be desiccant breaking down.
Limit the A/C use, as the compressor relies on the refrigerant flow to carry lubricating oil through it - long term the compressor will fail due to insufficient lubrication. If it's not noisey in operation now, it'll probably be okay.

Take it to an A/C place.
