On a 93 prelude what would cause th power door locks to go crazy and lock at anytime whether you r n th car or not and even if the keys r n ignition?

Answer 1

Not Sure. The locks are an electrical device and the motors are activated by switches. Are the locks a retrofit or original equipment?. First thought is that you have a "momentary short" but I think that's highly unlikely. Water pooling in an electrical area, even a little water, can cause mysterious electrical problems. Good possibility that THERE MAY BE A PROBLEM WITH A RELAY. The relay is a switch that is activated by another electrical device. The relay may be located in a "central" location with other relays in the engine compartment. Sometimes they are located under the dash. You can get a Haynes manual for less than $20 and look in the index for "relays". It will refer you to the "Electrical" Chapter with a reference to a particular page that will show the location of various relays that operate the car's electrical service items. At the beginning of the chapter, they'll have a glossary showing the contents of the chapter. You can go to the section on electric locks and read what they say about testing, or even, removal of locks. Sometimes they'll make reference to fixing problems. If you have any electrical T-shooting ability, you can go to the back of the "Electrical" chapter, where you'll find the wiring diagrams. You can find the locks and trace the wiring back to components in the circuit. Finding each one of these components physically requires you to look in other areas of the chapter. DO YOU HAVE AN ALARM SYSTEM? Some alarm systems activate the electric door locks as a service to the owner. If the alarm was a retrofit (non-dealer installed), it's very possible that there's a problem with the alarm system. Z
