Hello... hopefully a basic question which someone can help me with. Car is a basic 1994 Cinquecento & I've just noticed the wiper switches..front&rear never illuminate. The HRW & fog light switch are illuminated as soon as ignition is on and the heater controls illuminate when lights are switched on. Am I right in thinking the wiper switches should be illuminated at some stage...or is the current set up right? Have checked handbook, Haynes etc but can't see what correct set up should be. If I do need to sort out the lack of illumination any tips appreciated! Thanks in anticipation & stay safe.
