Yes, this is a pretty universal de-icer switch, on the outside of the evaporator case; you may need to take out the glove box to access. I agree to simply jump it, see if that works; if you get too cold, simply switch off the AC switch on the dash for a couple of minutes. When an evaporator gets too cold and the air is too humid, ice builds up on the evaporator coils, blocking the air flow.
If jumping the de-icer switch does not cause the compressor clutch to engage, next step is to check for (1) positive voltage getting to the pressure switch on the drier and (2) if positive voltage leaves the other drier wire, check for 12 volts positive getting to the AC compressor clutch.
A few weeks ago with the 1998 Frontier I'd lent to my daughter, I found a rodent had chewed through the two wires for the AC pressure switch and the horn wire, so I had to solder in some new patch wires. On that same truck like 5 years ago, I had to remove an AC clutch shim to get the air gap within specifications to repair that AC.
