Just bought a 1999 C280 for my daughter, and was doing the usual fluids and stuff. The car was parked a lot under pine trees so I was cleaning the vents along the bottom of the windshield.

I think this is a vacuum line. It runs along the firewall and there is a right angle connection on the passenger side that broke. Car seems to drive exactly the same. Is this a vacuum line for the HVAC?

What do I ask for at the dealer parts counter?

Thanks,
