AC Pressure Temperature Switch
I have a 2004 ML350. I need to replace the AC Presure Temperature Switch, which is near the radiator and the windshield washer reservoir.
Does anyone know if this year model has a self-sealing port? If it does, it means if I remove the old AC pressure temperature switch, the port would self-seal to stop any freon lost.
I have read that some model has this feature, but I need to confirm if MB made this feature available for this year model.
This would have the trouble of evacuating the system in order to install this new AC switch.
Your help will be greatly appreciated.

What tools do you recommend to read the code? Is something like the iCarSoft, Foxwell.. a good one? I also have a 2017 GLC and 2017 C300.
I figured it was the AC pressure temperature switch because the AC cooling fan would never turn on. When I supply power to the cooling fan directly, both fans work.
