There is no lo and hi psi switches on a 4640 unless they were added on but not from factory.
You may be right now that I think about it.
I was working on the 1086 at the time also.
I do remember having to add freon into the 4640 because it wasn't blowing really cold air.
The 1086 would cycle causing the red light to turn on inside the cab. (low freon also)
It was a couple of years back just after I got all my A/C service tools to avoid the high cost of the stealerships.
The tools have more than paid for themselves by now. |
