Hello. I have a 2017 Jetta S, manual transmission, 1.4T with approx. 130,000 miles on it. I am having a problem that so far 2 mechanics have been unable to solve: my AC cools initially but after the car has been running for a while the AC just stops cooling. When it stops cooling I am usually stopped a a red light. As the light goes green and I start going again, it may start cooling for a little while, but that does not last much either. After a little while it is just blowing warm air, no cooling at all even while moving. The system was recharged with freon. Did not work. The compressor, drier, expansion valve and pressure sensor were all replaced. It is still doing the same thing. Any ideas on what could be causing this? Thanks in advance for any guidance you can provide.
