Why do I have no auto night headlights, no electronic mirror adjustments and no auto locks. They all quit on my 3/96 4.6L single cab f150 lariat, why?

after all fuses and relays verified are working it sounds like you have keyless entry on the door panel with a keypad and in either case theres a driver door module inside the door panel this may have gone or the fuse for that has blown I'm ssuming that you have the owners manual with the diagrams if not ford owners .com register then download your manual then go to roadside emergencies and the fuse and power distribution box diagrams are there also this could be you headlight switch so if the fuses are all good then lookat the door module on the drivers side next to the speaker or the headlight switch do the windows work also check the master window switch this is because all components have some borrowed power from other wire circuits so look carefully at all of these even a corroded wire or contact can cause havoc on other systems clean al and a light dab or spray of wd40 will help you good luck Stephen

Look for broken wires leading into the driver's door. Have you already checked for a fuse problem? The windows and locks may be fused, or they may be on a circuit breaker. Sounds like power is not getting to the master switch, or the ground for it is lost. If you have a voltmeter, you can check for power and ground right at the master switch. The switch will have one hot wire to it with the key on, and one ground wire from the switch back into the cabin and then to ground somewhere, probably close by.
Ground a voltmeter or test light, pull the master switch connector apart, turn key on, and probe the connector for one hot wire. If you have it, good. If no power, again check for broken wires at the door. To check the ground wire, put positive lead on the hot wire, and the negative lead into the ground terminal source at the connector. If the ground is good, the meter will show battery voltage, or the testlight will light up. If the ground is lost, you will get nothing on the meter or testlight.

What would causw both electric front windows on 2005 caliver not to work? Already change out switches in the middle of the consel??

I would be willing to bet be willing to bet that you did not check for power and ground at the window switches before replacing them.
Please read this article before continuing: What Else Could Be Wrong?

I am assuming that you have the 4 door model since you specified "both" and "front". So this advice will be based on that. If you have the 2 door version, this could be very different.
If the rear windows are working and the front windows are not, that eliminates both the power source from the circuit breaker to the master switch and the ground circuit to the master switch, The only "component" that could cause both of these circuits to malfunction at the same time would be the master switch. You could, however, have separate failures of each of the window motor circuits between the master switch and the window motors. GM has had more than their fair share of window motor/regulator failures. This type of failure is not likely to occur on both sides at the same time. This would more likely work something like: Passenger side quits, then several weeks or months later, the driver's side quits. You could also have broken wires inside the umbilical between the body and the doors. With the older cars with the master switch in the driver's door, one broken wire could take out both doors. This does not apply to your vehicle, however. Again, this would also not be one of those things that would cause both sides to go out at the same time.
So to wrap it up, you need to check for power and ground moving into and out of the master switch at the correct locations and under the correct switch operating positions. This will require you to get your hands on the wiring diagrams for your power windows so you know what is what.
If the power and ground is ok at the master switch, then you need to remove your door panels and check for power and ground at the window motor connector. If you are missing either power or ground at any point, then you will need to do a wiring repair. If power and ground is available at the window motor connectors, then you need to replace your window motors and/or regulator assemblies.

2-door diagnosis is similar, but you cannot eliminate "source" power and ground to the master switch by operating the back windows. You will have to test for it at the master switch.

My 2003 elantra all 4 windows stopped working. checked 30 amp fuse in dash.. was good. checked relays box with fuses in it under hood. Didnt see anything blown. What else could cause all 4 windows to stop...

Wiggle the wires going into the door from the pillar where the door hinges are while trying to put the window up or down if nothing happens then change the master switch.

All the power windows quit working, the fuse is not blown. i thought it may be motor but, all the windows quit working at the same time.

It's either a master fuse for the whole window system (if your car has that) or it's the switch module on the driver's door. All the window power is routed first to the driver's door, then out to the others. If your master switch on the driver's door dies, you'll lose all the window controls. Check fuses, and if they're OK, replace the driver's door switch panel. Once you do that, you should be fine.

Power windows stopped working.

Likely a bad master switch (the main window switch located in the driver's door). All other switches seek ground through the master switch so the effect quite often is the master switch can cause loss of window power on other doors. Given that the driver's window has also now quit makes this switch even more suspect.

Camry 1994 power windows dead!

It is rare that the circuit breaker fails.
What I would do if I were you, is to check to see is the 10 amp GAUGE fuse (under the dash) and the 50 amp POWER fuse (in the fuse box under the hood) are good. If both fuses are indeed good, the next thing that I would do is to check to see if you have 12 volts power in the BLUE wire going to the driver side door switch, in the harness connector, that connects to the main switch. If you have no power in the BLUE wire, you have a broken wire between the body & the door harness. This is quite common. If you DO have power in the BLUE wire, replace the driver side master control switch. if the contacts in the DRIVER's part of the master switch fail, there is no power transmitted to any of the other windows. Hope this helps, and thanks for choosing FixYa. Please feel free to comment back if you need any further info.
