To repair the wiring on the trucks door locks, you will have to find the problem first. Check all of the wires connectors for loose or bad connections, and look for any places in the wiring where the insulation has worn through.
In the back of a Haynes repair manual or autozone.com there you will find online repair manual's
Probably by checking the wiring loom and connectors for damages and and corrosion.
There is an electrical problem with the switch or wiring. Have it checked out/
PCM, Relays, Power locks, wiring
In a Honda Integra, you can convert manual locks to power locks. You can either purchase a kit and do all the wiring yourself, or you can purchase doors from a junk yard and redo the kit. By purchasing doors, the wiring is already set up.
If it's not the fuses or electrical relays, the short-out probably damaged some wiring. Take it in for an electrical check.
Pick up a "Haynes automotive repair manual" at any local auto parts store (AutoZone, Advanced Auto Parts, Etc.). They have wiring diagrams in the back of the book. Should cost about $15.
The 1990 Jeep Grand Cherokee power locks wiring diagram can be obtained from most Jeep dealerships. The wiring diagram can also be found at most auto-parts stores.
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
If you wait long enough the problem will not be intermittant anymore and you can fix it. Sounds like an electrical problem to me if they all are doing it and the problem should be in the driver's door. I would be looking at the wiring harness that goes through the rubber boot tween the door and the body....that's where the most flex in the wiring comes from.
you must have cut wires inside the wiring harness between the trunk and body. open trunk and you will see a rubber cover for the wires on top. open it and repair the wires.
U need 2 spray the inside of the power door lock switch with electrical contact cleaner or repair the loose connection on the back of the switch
