The C5 has rain sensing wipers which sometimes act like this if the sensor which is in the middle of the windscreen at the top is obscured ie the glass is dirty.

I've diagnosed and repaired this problem twice on C5's. Both times I had to replace the wiper module (it's the printed circuit board mounted on the wiper motor).

Why did you buy a switch? Did the original one meter out bad? Never replace any part till you understand how it works and how to test it. Work the wipers and the lighting issues as two separate problems. The wiper motor or relay etc may have failed around the same time as the heater core. Two separate things Unplug the wiper motor and turn the key on. Meter out the connector in different switch modes. Need a schematic of the circuit. Lights-- Problem is after the fuses and they are the start of most circuits. so you know you have an open circuit like a connector under the dash you disturbed unknowingly during the heat core deal or a loose ground wire.

tighten the wiper arm nuts vw know for loosenign up. don't wipe ice off or it will happen again

check wire continuity with multimeter, have had switch go out on ranger as well.

well the good thing is you know the wipers work !! , I would start by seeing if the washer squirters work when using the Wiper lever . and I would also see if it worked on fast speed and slow speeds . If it does you may have a wiper switch that has gone bad ! ,

there may be two relays but you'll need owners manual to know for sure. yes there is only one fuse for the wipers, i thought you didn't know which one it was. but i'd check them all any way just to make sure. sometimes several things are on a fuse. if it's not that i'd say it's the wiper motor. try wiggling the wires connected to it and see if they come on.
