The Mercury Villager enjoyed a decent run as one of the more affordable mini-vans, but is no longer produced. These family vehicles share a lot of the same parts with their sibling, the Nissan Quest, which can come in handy when repairing an electrical system.
Reprogram your Mercury Villager alarm remote by getting inside and closing and locking your doors. Place the key into the ignition and remove it six times very quickly. Once the instrument panel flashes twice, put your key in again and turn it to the accessories position. Push any button on your remote, and it should be programmed.
Locate the keyless entry module behind the center console if you need to replace it. You'll have to disconnect the negative battery cable first.
Replace power window switches when a power window doesn't work correctly. Repairing them rarely works as they break off quite easily.
Consider replacing the oxygen sensors if it feels like your Mercury Villager is riding a little rougher.
Look at your back brake lights if your dash lights up when you brake. If you'll remove the brake light bulbs, you may find that the solder melted together at the base of the bulb. This leads to a voltage program throughout Mercury the electrical system. Replace the bulbs to fix the problem.
Investigate the brake lights again if strange electrical things keep happening. The base of the brake lights gets incredibly hot, which can lead to a short throughout your Villager. This problem can also arise if the wrong type of brake lights are installed or if the right ones are installed incorrectly.
