Just finished the 1200km trip to Portugal without any significant issues, but at one of the stops I realised my partner's white sneeker was yellow/green. Went to check the passenger foot area and there it is, a leak. There were just a few drops of coolant on the duct ends and the carpet wasn't that wet, but something is leaking for sure.

I've read a few threads on this, both just now and way before buying the car. I'm aware that it is an involved job, but maybe not really how involved/difficult it is.
A few questions:

1 - Is this mainly a time consuming related thing? Or are there parts that are difficult to take of etc?

2 - Given I live in a hot country and it's summer, can I just bypass the matrix from the side of the engine bay and does this interfere with the AC making cold air?

3 - Besides time (I would do it myself), is this an expensive job in terms of parts? matrix, hoses, etc
