Sounds to me, like you have a low amount of Freon in the system.Hi,
So I have an 02 TB just crossed 150k the ac issue I’m having is it runs down to 45F and is usually fine unless the temp is hot outside over 80f. Or it will be cold for about 20/30 min then won’t blow cold. I have checked the Freon level it is full. The compressor will kick on and off. I have heard about getting the system pcm flashed By dealer. Where is the air intake for the cabin is it On the dash just outside the windshield? Also does the 02 TB have a high pressure cut out? Is there any sensor for cabin air temp? Finally does the ambient air temp sensor tie at all the the AC temp? Thanks again sorry for so many questions.
Someone probably didn't shake the can, and forgot to hold the can up-side down.
Which causes Compressed air to go into your system, instead of the Freon.
( you check the pressure with the gauge of the can, while can is up-side...up.)
Watch a youtube video on it, keep in mind depending on the vehicle, Most have to be running full blast while filling.
If you live in a very hot state, or haven't driven in awhile.
don't turn your AC on Full blast cool right away in the hot summer, otherwise you will get too much condensation/moisture.
Turn it to slightly below medium (70) for about 2 minutes on high, and then cold.
