Lmackattack Posted February 15, 2006 Share Posted February 15, 2006 QuestionI have the old style wiper motor on my RS. ( looks like a half moon shape). the air valve switch was faulty soI went to the mack dealer and they said there is 2 style switches. they gave me the "new style" that is slightly smaller than the original one. are these switches interchangable? they look like they will hook up the same way but will this smaller "new style" switch operate the air motor the same?

terry Posted February 15, 2006 Share Posted February 15, 2006 I think the old style twists to turn on and the newer style pulls on and pushes off.

Barry Posted February 16, 2006 Share Posted February 16, 2006 Yeah, you should stick with the old style...Tell them you need a 7623-7547070 I have several on stock if your Mack Dealer doesn't.
