Q: Blower Motor Problems on 1999 Buick LeSabre

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Does the cooling tube on my blower motor serve a purpose? I am missing the tube and wonder if i'm doing any harm not having it.thanks in advance.

I think what you are referring to is a black rubber tube that allows coolant to vent away out the firewall in the event the heater core would fail instead of just having it flow through the heater motor and onto the carpets.
