Hi guys. Look at your old switch to see if two terminals are black or overheated. If they are, the mating terminals in the connector have to be cut out and replaced individually.
The voltage missing on fuse 14 comes through the dimmer portion of the switch assembly. (Be sure the switch is turned on when you're checking for that voltage on fuse 14). Since that is missing, you will find it's also missing on the brown wire at the switch connector. That's the wire that feeds the tail lights. We know both the tail light and dash light circuits aren't going to develop their own problems at the same time. Instead, your old switch is defective and the new one is the wrong part, or there's a break somewhere in what they have in common. That is the orange wire at the switch.
Check for 12 volts on that orange wire. If it's missing there, that wire has a break in it, either inside the fuse box, or at the terminal in the switch connector.
