U can get them new from online dealers. Master switch is about $35 & others are about $10. I got lucky and found mine on eBay for only $17 shipped. I found some for about $30 - 40. Part numbers are 04602780AA for the driver's master switch & 04602787AA for the other door (all three door take the same switch).
If you do a Google search "caliber window switch mod" & click (I think) 1st link, should be a post from calibersrt4 forum. It shows part numbers, pic and DIY which is the same for the compass.
