A/C Issue

[mydirtytruck]

My e99 a/c blows like a champ....until i get in heavy stop and go traffic. After a few mins, or when i get going again, the compressor kicks back on and its cold again.

I dont know anything about a/c systems, but it almost seems like it could be a relay heating up or something causing the compressor to kick off due to the heat, but when the airflow is back, it starts back up. Anyone have any ideas? I live in Fl and its dang hot already!!!

The compressor has an air gap in it between the clutches. The clutches last so long that they wear down and don't contact well anymore so you have to shrink the gap in there, and it works again.
That's what mine was, and a lot of others were too

How in the world do you go about doing that???

When the truck is running and the AC is On, but not engaged as it should be, try tapping on the clutch face. If it snaps On and stays On, the "Air Gap" has become excessive. Not hard to fix, you just shim it. Try the test first then search Air Gap for how it's done.
