Dealer AC repair?

I never had much luck with dye on very small leaks. Probably operator error.

 

Soapy water test? Are inspecting a tire for a flat repair? Ha

 

Evaporator been a known problem too. My 2010 had to be replaced a month before my extended warranty expired .
Yea seems like symptoms of low on charge is colder on drivers side and warmer on pass side .That threw me off lol

 

I remember my truck having this issue before. Blowing cold on driver side and warm on passenger side. Took it to the dealership and tests showed a leak in the line. Known TSB. Failed o-ring in the line. Replaced o-ring and recharged the system. Blowing cold ever since. Hope this helps. Good Luck!

 

How do I find out if mine is a TSB maybe they will replace it? Do you remember which line and which o ring?

 

I highly doubt your ac will be warranted on an 07 when it’s 2019. Follow the instructions given, check pressures, and so forth. If you have or buy manifolds to do the actual pressure checks you will be way better off.
