Has anyone here had to replace the leaking evaporator unit under the dash in there gd jazz? I got quoted over 2k to fix it, apparently genuine part only (about $700)

Obviosly im not paying 2k to fix the ac in a car that's worth 4k so i'm hoping i'll be able to do most of it myself, I was told its a full dash out job.

Hoping someone has gone through this who can shed some light.

Of course the a/c has to shit itself right in time for summer... thanks obama

If I can get the part from the US for 500 or so dollars and do most of it myself then pay to have it gassed up and test ect it might be worthwhile, but 2k, I would rather just sell the car lol
