That's what i first concluded from readings on the web, yet the hiss of escaping refrigerant suggested otherwise. Unless there's a valve type mechanism on the r/d that engages once the switch has been screwed out far enough. Or the AC shop slapped in some cheapo aftermarket r/d which has no barrier between switch and refrigerant.

There are two types of temp switches. One connects through to the refrigerant and one does not. (Some aftermarket receiver/driers have ports that will accomodate either version.) We both know which version you have.

On my '82 300D, engine compartment heat, on a really hot day, will occasionally trip my switch, even with the a/c not in operation.

It would just be annoying if it'll still not work after putting in a new one. Could there be an issue with the dryer?

None that I could envision.
