Just because a parts been changed doesn’t necessarily mean it can’t fail again, especially if cheap aftermarket parts are used.

And it’s possible you could have more than one leak in your ac system, and now you’ll find the next one with the dye.

Either way seems like the shop will sort it out for you, and any leak will be found easily with the dye they added

Not sure if what i’m saying is possible but im just throwing ideas out there. After removing the final stage resistor, or the blower motor, the evaporator is visible. On a dark night with a UV torch you might be able to see leaks in there if any are present.

It’s not much work to remove either part and it is definitely a DIYable job.


here’s some info on those jobs
