How to change the license plate light on 2001 ford focus zx3

The license plate lights get B+ power from headlamp switch . No seprate fuse for those lights , Bulb's good ? Headlamps , park lamps all work ?

Use a screwdriver in the recess on the plate light. Pry out the light unit. Release bulb from the contact spring. Install the bulb using a reversal of the removal procedure. Make the tension of the contact springs sufficient to hold the bulb firmly.---------------------------------------------------------------------------------------------

kind of tricky, took me an hour to get it figured out, but you got to open the trunk and take out the 10 or so 10mm nuts sticking out of the backside of the lid, then the whole solid piece where the lights are on the back will slide off, then you can change the bulbs above the license plate and put it all back together, im cant remember off hand the bulb size, but your local auto parts store will have that info when you go to buy them

Sounds like something is connecting to the car body, I would inspect the bulb you changed make sure the metal clips or wires are not touching anything.

a loose or damaged wire is causing a short circuit!
you ned to get it tested & rectified by a auto electrician ASAP!
as wiring gets very hot & can destroy your vehicle! {catch fire]

I'm assuming you mean the rear license plate bulb?

Depends on if you have a coupe, sedan, or wagon.

Here's a link to the owner's manual. Start on page 247 and use the procedure that's right for you Focus type:

if you buy some of those "on tv only" lights that are bubble shaped and plastic, you can duct tape those onto your license plate area and click them on or off when needed.

try taking the inside trim off inthe boot there should be an area were u can get at the bulbs with out taking the whole light out

remove the whole unit its only a couple of 8mm nuts from the inside 15 min job including *** break
