I have a 2003 Ford Focus ZX5. The new license plate holes do not match the ones on the vehicle. Why and what to do?

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.

1- Have you replaced the interior cabin air filter, it
could be all mildewy
2- there is a can of vent spray you can get to spray directly into the vents(follow the directions)

These are only possible answers.

disconnect the battery & make sur you have your radio code, then remove the belt.
it's pretty simple there's a nut in the middle of the tensioner wheel, get the right size socket & using a ratchet, move the tensioner by locking the rathet & do or undo the nut, as it's a fixed nut used to swivel the tensioner.
Then undo the wiring on the back of the alternator, usually a click in multiplug and a + power cable boted on with a 10mm nut.
then remove anything in the way of the alternator securing bolts, & remove the bolt's, alternator should be free !
But I don't suggest you do it yourself unless you have a reasonable grasp of mechanics, as I have had to do this job properly after some people have tried themselves & they've made it worse, plus once the belt's off you have no power sterring so you can't drive it to the garage if you can't get the belt back on !

Its usually on top of the gear box and there is usually a black or grey plastic top you can take off.

SOURCE: which wire is constant power 4 radio in a ford focus

all you need is a test light
turn your ignition off
check all the wires with the light
there is one wire that has power
that's the memory one
then turn the key to the second knot
check for the next one that have power
that's the one that will power up the system
