Probably a bad resistor on the motor circuit. The fact that it works on high is an indicator. Go to Nissan Frontier / Navara Forum (http://www.clubfrontier.org) and search for your topic, tells you part number, location and how to change the resistor pack.

Bad resistor, which may be part of the switch assembly.
