Review on 🔧 Ford D7OZ-19A563-A - High-Quality Air Conditioner Valve for Superior Performance by Adrian Smart

If your cabin exhaust air switches to continuous de-icing then it is because it is defective or the vacuum line is cracked or defective. A plastic vacuum line costs up to $1 per foot. Just make sure you need 2 ways. Some Ford modules have a path. Just plug the other nipple with glue. but chances are your Ford Merc Linc 4.6 or 5.4 will require this part. The plastic will become brittle and any tension from the cables can break the nipples. This is an instant fix. Welcome back. oh, it's on the firewall in the corner next to the air conditioner evaporator, you should hear a loud hiss around it
