hey what's up everyone welcome to my
0:02
channel Today we're diving into a super
0:05
quick fix that could save your summer
0:08
How to find and check the AC compressor
0:10
fuse and relay on a Ford Focus That's
0:13
2009 through 2021 models So if your C
0:18
suddenly stopped blowing cold don't
0:21
panic Before you take it to a shop or
0:23
start throwing money at it let's knock
0:26
out this easy DIY check first It's cheap
0:30
it's simple and you can do it with just
0:32
your hands Maybe a multimeter if you're
0:35
feeling fancy So let's get to
0:41
work All right first stop inside the
0:44
cabin The fuse box is located inside the
0:47
panel on the steering wheel area You
0:50
need to remove the cover by pulling that
0:52
out to access the fuses Then pop open
0:55
your fuse panel and you'll find the
0:57
fuses So here is the fuse that you need
1:00
to check Check out these two 10 amp
1:03
fuses right here Now they aren't
1:06
technically for the AC compressor but
1:08
they power the AC interface and control
1:11
system So if these are blown your AC
1:13
won't even think about
1:18
working Now let's move to the engine bay
1:22
fuse box Here's where the magic happens
1:25
First check this 10 a.m fuse This fuse
1:29
right here is dedicated to the AC system
1:32
If this one's blown it's game over for
1:34
your compressor clutch Next check this
1:38
relay right here That's your AC
1:40
compressor clutch relay If your clutch
1:43
isn't engaging this little guy might be
1:45
the culprit Try gently tapping the relay
1:48
while the AC is on If your clutch kicks
1:51
on the relay was probably stuck Want to
1:55
confirm it swap it with a known boot
1:57
relay like your reverse light relay If
2:00
your reverse lights work you know that
2:03
relay's good Swap it in here and see if
2:15
up In the 2012 to 2018 Ford Focus you
2:20
can find the AC fuse in the cabin fuse
2:22
box Pop that hood and head over to the
2:25
driver's side We're looking at the main
2:27
fuse box right here So here are the
2:31
fuses The fuse we're hunting is F27 It's
2:35
a 15 AM blue fuse and it powers the AC
2:38
compressor clutch If it's blown that
2:42
clutch won't engage And no clutch means
2:44
no cold air Next up check the AC relay
2:49
That's R11 just below it Got a
2:52
multimeter great Test it If not grab
2:56
another identical relay from the fuse
2:58
box swap them and see if that fixes your
3:01
AC If your AC starts working again
3:05
congrats It was just a relay Now grab a
3:08
new one and you're golden If not we may
3:11
be looking at low refrigerant a leak or
3:14
a bad compressor But always start with
3:26
Now for the MK4 the AC fuse can be found
3:30
in the engine bay fuse box It is located
3:34
between the near side wing and the
3:35
battery You can see how you can access
3:38
the fuses in my other video So in this
3:42
fuse box you want to check this red fuse
3:45
It is a 10M micro 2 fuse that is
3:48
responsible for the air conditioning
3:50
clutch You can spot a blown fuse by
3:53
looking for a break in the metal strip
3:55
inside Ensure you use the correct fuse
3:58
type when replacing it Always check the
4:00
amperage rating If your power outlet
4:03
still isn't working after replacing the
4:05
fuse double check for a loose wiring or
4:07
try testing the socket with another
4:14
And that's it If your AC isn't working
4:18
don't just jump to recharging the system
4:20
Check your fuses and relays first It
4:23
could be a 5-minute fix If this helped
