hi good morning my name is Caillou I'm

from Brazil I try help somebody else

with problemo

- with you the Cadillac mm devil morph

star okay my problem here is basically

no works they lock the doors

the button in the door here okay

in the - no works the trunk is a gas

tank door here okay so I show here

turning the ignition here there start

the car

so happy any called now fear their check

engine light soon but it is this one

4300 these normally is the problem they

may fold had some a leaky there and the

Maypole here here's a nice hole normally

have a silly leaky side here in the Phi

you know the five here so that it is

twice usually spray with the scope

you'll find some bubble now they have

the leak okay

but it is a calculator for now I am a

focused in a problem with the ball off

the front and the lock the doors either

gas tank okay so basically you need to

make sure they're really is good for it

okay and in the Cadillac you'll have one

fuse box in under their rear TT here

you'll see there were your speedy here

so disassemble it okay you'll have it is

here okay

and you have one second this yield box

in the prone to the car visual here you

throw to the car okay

you'll have other few boxes but in the

manual we pair then show the problem is

here in the rear seat okay he'll check

the diagram here because when you have

the Box the Box coming from like it is

okay you're already here

you'll see the big feels here it it

feels the bigger fuses there okay so

this is the diagram position either

really 52 in 50 this 52 here 52 and the

fifties the fifties he controlled the

gas tank and the door okay if 52 is the

trunk so you remove you won okay

the removal one you make sure they're

really is will be first because the more

you to change the ruling how you're

doing to check what it is good there is

not you'll take one transformer from

transformer like it is okay

he'll take you one more word you'll see

they call this or the pings 85e

deep so try show here but it has never

will eighty five eighty eight seven and

thirty okay normally open it is 3087

and the 85 the 86 is the magnet okay so

to take you to more multimeter or

multimeter you put the multimeter

selected in 1408 compete over here okay

make sure you work for it look you're

okay

20/20 only 38 788 7/3 Oh works okay

don't have computer here but you use it

for you use the 12 volts here he 85 cat6

no matter if it's positive and negative

because it's just one red says you'll

hear one little click you hear the click

this means a work but it is not many he

makes it continually you need to make

sure with a multimeter if they continue

it

you're here so this really is good okay

you're told

eight seven and thirty is all you see

here he's doing continuing okay this

really is good okay

you are sure there really is good you're

going ahead you're going there in a box

the fuse box again

okay make sure he have a co-occurrence

there okay also take over a bitter man

like is another hundred again I put it

well votes from Chino its current when

is looking for type water quality here

even black there

okay so I have

like what the great

I had a 12 volt so 14 volts because in

this case the alternator working he gave

it to me 14 volts but if you turn off

the car no for simple heavy 12 it's just

for cause the alternator okay so this

means we're heavy currents 12 volts the

position really is age 7 eternity there

ok because some people then share the

position really poor people they really

like this is wrong no use there really

like this because the position with the

7/3 going in the correct position is

this position the really ok important

you respected position really there

really if you change position then go 85

in seeking incorrect position ok very

important respected position really is

this you check the name here what's

wrong ok he going there it is not

original really you buy all the one new

one you know coming to the name here but

you need to show respect to the position

87 be 38 7 is here

the third is there okay so everything's

working good you have a current here ok

12 volts

but us what are the second is the 30

step the third step make sure the

throttle works so you disconnect to hear
