A/C Leak Drivers Side footwell

Hello folks,

Since I've owned my ZT, I've noticed a green residue on the sidewall of drivers side footwell. I've never really payed attention to what it was, as I believed it was left over residue from an old coolant leak, as the Matrix is around that area. However, as I got into my car the other day, I noticed a fresh drop of this green fluid on the footrest. I then wiped it up and noticed the colour looked highlighter yellow on the paper tissue. After posting on the Facebook groups, I have been informed that it's dye from the AC system, which would make sense as I have been using it lately. It's also not as cold as it was when purchasing the car. I bought a UV lamp to confirm this is indeed AC liquid, and it appears so. I cannot seem to find any Air Con diagrams online, or anything relating to the Ac system, so I can figure out where the lines are leaking. Would anyone have any idea where this leak could potentially be coming from?

Hello Adam,

The refrigerant pipes to the evaporator pass through the driver's footwell alongside the heater/AC unit. If you remove the trim panels you'll see.
