Recurculation button

Pressing this button doesn’t change a thing : still getting these awful smells into my car (trucks !)Anyone with the same problem ???Eric

No effect either:1. Smelly trucks2. Gets no colder with the con air working with recirc button depressed vs without depressed and my con air definitely works (well just).3. Still get the draft on the knees.4. No whirring noise of a motor closing the duct - if there is one?

You don’t think it does anything, do you? It’s only there for you to play with when you’re stuck in traffic jams! [image][/image]
