no heat for second row

[drtyjerz47]

hey guys, this is my first thread. i drive a 1999 4runner limited, v6 4x4. currently my issue is i do not get heat out of the rear heater thing by the console. it blows cold air even if the lever is all the way to hot.

any suggestions?

Rear heater lines are corroded or they have been bypassed by a previous owner. It's common for them to rust out. Easy fix is to bypass them

Rear heater core could be clogged as well.
