Why power door locks don't work on 1993 Ford Tempo?

Answer 1

Make sure you have voltage to the master switch and any subseuent individual door switches. If the switch is not "clicking" when you depress it, and you have voltage to it, the problem is more than likely in the switch itself. You can take it apart carefully and check for proper alignment and corrosion. If the switch is working and allowing voltage thru the contacts--check the solenoid in the door. Check for voltage on the solenoid connector wiring terminals when you depress the switch. If you have voltage then you either have a bad solenoid (check by supplying voltage to one terminal and grounding the other--then reverse the connections) or bad wiring to ground. I'd personally check the solenoid first for voltage and work back toward the switches
