Rear heat system

[Z71snow]

Hey I have a 03 z71 Tahoe and I have a leak on one of the lines that’s connected to the heater core. The leak is under the rear passenger side door. Is there a simpler cheaper fix that I don’t have to take it to a shop

iirc them lines run in the rocker panels, ac lines and heater lines.

Welcome to the Forum from NH.

Pics of the truck, please.

There was a recent post regarding this issue, nd I believe that the recommendation was to splice a new section of line to replace the section where it is leaking.

Other folks on the Forum will chime in with their thoughts.
