2005 AC Pressure Switches

[stormnorm]

Do you have to evacuate the system to replace the ac pressure switches on a 2005 with a 5.4 or do they have schrader valves?

On my 2004 the high side pressure has a schrader valve and thus does not need to be evacuated. The low side does not have a schrader valve and needs to be evacuated to replace.

Thank you for the information
