Roomster , fan/blower speed selector?

I Pulled the fan speed selector off a few weeks back which was to check the switch  because i had a problem with the fan,  but it wasn't the switch that was the problem and was the resistor so its replaced,  for a week the though the blower was working fine although the selector switch was temperamental in that some times I'd need to tap it to get the fan to work. Pulled it apart again and unfortunately I'm pretty sure I've lost a connection that was likely a copper tube I'm guessing , now the switch doesn't work atall.

So here's the question: 

Where do I get just a new selector switch or better still the copper connector tube ?

I realize you can buy the whole climate control but it seems a bit ott when I only need 1 switch
