ETR switch (Evaporator Temperature Regulator)
This device causes the A/C compressor to cycle on and off, in order to prevent "icing" of the evaporator core.
NO LONGER AVAILABLE, DISCONTINUED BY MANUFACTURER AND VW IN MAY 2006
The 1995-2005 version of this switch is still available and can be adapted to fit, as both of these switches have just two eletrical spade connectors. See below

The 1992-1994 version of this switch (VW part # 191 959 281) has been discontinued by VW and is no longer available.

only two small spade type electrical contacts used.
