Question Unknown green wire under hood. Has been cut. Anyone know what it’s for ?

[Rich W.]

I was thinking shrink wrap applied properly might offer a good solution. If the Lt ever checks back in he’ll have all kinds of options.

A Marine grade wire terminal shrink connectors. They have heat activated sealant which is waterproof and should make a good seal.. That sounds like a good idea.

Of course the best solution is to replace the line with a more durable material as suggested by Pem.

"Of course the best solution is to replace the line with a more durable material". Yes, ideally. Unfortunately these lines, especially the HVAC ones, tend to wind around in the conduit covering wire harnesses making full replacement very much not worth the effort. In our original poster's picture we can see one end going into said conduit and the other disappearing into the firewall. Probably doesn't merit full replacement in this particular case. But if you wanted to replace and upgrade it I've used silicone vacuum line with good success. If I recall correctly "4mm" is the size of the roll I bought and have been using for years. (It also works OK, but not great, for IDI diesel injector fuel return lines.)

Agree this appears to be a tube. Tube could be from EGR or could be from HVAC system for changing venting
