its time to seperate the mopar men from the boys
We STILL don't know what year/ model you are working on
That is the "evaporator temperature control switch" and the cap tube will be slid into something, probably another blind tube, which may be full of grease, on/ in the evaporator. Unless the cap tube is rusted/ corroded in place, it should pull right out of there.
You can indeed temporarily bypass it, but you'll have to watch the coil for freeze-up.
Here's how a switch like that works. That "wire" is a sealed tube, full of some sort of gas, depending on the temperature. Higher temp means the gas expands, and bears against the diaphragm at the switch, so in reality, it's actually a pressure switch. Some in the refer industry are adjustable, and in fact a commercial refer pressure switch often looks exactly like a pressure switch, except the pressure switches come with a 1/4 flare nut (usually) and the temp switches have a sealed "cap tube" just like the one on your evap.
