ML 270 Air Con ~ Is there a Check Window?

[LozML270]

Hi Folks,

This is my first winter in 6 years so I can't remember what to expect. I turn on the A/C and it fogs a little then clears slowly the windscreen and other glass areas.

When I was in South East Asia, A/C was critical so everyone knew to look for bubbles in the little check window of the system for when a regas was required. I wondered if those same check windows exist on systems over here and if so, Where is it on my ML270?

Alternatively, is it normal with this cold weather for the car to fog up in side on start up and then take a minute to clear with the A/C set to demist?

Until I read your third sentence I thought that you'd hibernated for the last few years

Yes, it's normal for the car to fog up when cold.
