Question about power seat?

[AnthonyF]

Are these direct replacements? Did you car come equipped with power seats? Check to see if you have power to the switch. If power is in the switch, switch is bad. If there is no power getting to the switch you can either:

A. Find why there is no power
B. run a direct 12+ wire to the seat

My new seats are off a maxima same year as mine so they are direct replacement, and my original seats weren't power, but all the wiring is there already, I jsut had to hook it up. Which I did. The passenger seat works perfectly with power and everything, but only 1 of the 2 switches of the drivers seat works. How can I check if there is power to the switch? When the switch that doesn't work, nothing happens, does that mean it has no power?
