A/c drain tube

where do i look for a/c drain tube on 94 nissan v-6 pickup and how do i unstop it? thanks

The drain tube is on the firewall, low on the passenger’s side. You may have to get under the vehicle to see/reach it. Push something up through the tube to clear it, or try compressed air.

Most cars have them under the car in front of where the passenger puts their feet.  Compressed air or string trimmer string from the garden center are the usual tools of choice.  Don't use wire as it can damage the drain hose or the evaporator unit.

thanks to you both. i found it and used a stringer line and it is draining.
