Welcome to the forum! I hope this job isn't too labor intensive! Please keep us updated.
I've download the manual from here: 2008-2015 TOYOTA iQ Service ManualHow do u remove one do u have to take the dash apart I'm trying to locate answers on replace and remove evaporator core on my 2012 Scion IQ
Sorry for not updating, the parts took a little to arrive to my country but with all parts in hands I'll keep you updated
The main reason why failed was the expansion valve and there was a big leak on the old core, here in my country instead of buying the original part the mechanics try to fit another similar. So I don't think the original could failed that easily, with good maintenance it should last the car's lifeany idea what caused the failure? I hope this isn't a common issue with the IQ. Good job in completing the task. I got a headache just looking at your picture.
