AC not working too good.

2019 F150 XLT 5.0. 46,000 miles. Noticed my ac not working too good. I put a temperature probe in the center duct and can get it down to 56 degrees in the duct. But in traffic it will go up to 69 - 70 degrees. Also sometimes while driving at highway speeds it will stop putting out cool air and put out ambient air for about 10 seconds. Suggestions?

You need to go get it looked at, be warned it's not a easy system to work on. It also requires very expensive equipment to service. The system is filled with R1234YF not R134a.

I adjusted the air gap on my compressor clutch a couple of years ago and it made a very significant difference. Also, you may want to check your engine coolant level.
