Yes, I believe so. There's two switches on the accumulator or dryer. One is a pressure switch & the other a temp. switch. The cycling or pressure switch will require the charge to be lost though (Don't believe there's a schrader valve below it) It does not cost that much to buy. This is on a W123? or 126?
By the way, your location, by Joshua Tree National Park in Calif? Paul.
