Yes. I'm hoping, however, that they will have checked those before condemning the evaporator? With the latter being hidden, the dye is no use, so I guess they've poked a sniffer down the air vents to diagnose it? I'd be gutted if someone ripped my dash out to change the evaporator, only to find that the sniffer was picking up a leak from a union that had been sucked into the cabin airflow by the heater fan!
