vwcrazynm :

so your blower motor is working but you dont have air out of the vents, is this correct?

Customer:

correct

vwcrazynm :

okay

vwcrazynm :

so their is a service bullitan for that car

Customer:

what is that?

vwcrazynm :

it is a know problem that the dealer releases

vwcrazynm :

it sounds like a sensor problem

Customer:

is there no relay or fuse that could be out?

vwcrazynm :

does it blow hot air or does it feel like no air is coming out at all

vwcrazynm :

if the blower motor turns on then no i dont think it is a fuse

Customer:

for the past couple of days, thge ac has been turning off and i would wait for a few mins, and it would cut back on byitself, this morning was the last time the ac turned on

Customer:

my buddy was able to test the blower motor by hooking up directly and the fan turned on

vwcrazynm :

okay

Customer:

thats how i know the blowermotor is good

vwcrazynm :

so it works if you bypass it but dosent work by the controls on the dash?

Customer:

correct

vwcrazynm :

okay im sorry i was confused

vwcrazynm :

then yes it does sound like a fuse

vwcrazynm :

let me check to see with fuse is for the blower

Customer:

i've checked in the owners manual and i didnt make sence

vwcrazynm :

okay check fuse number 16 and 22 inside the car on the drivers side of the dash

Customer:

it called for fuse # 22 (40) to operate the fan, when i checked the fuse box in the driver side dash, #22 didnt have a fuse in it

vwcrazynm :

22 is for the blower motor

vwcrazynm :

no fuse?

Customer:

let me check 16

Customer:

fuse 16 shows good

vwcrazynm :

you should have a fuse in number 22

vwcrazynm :

put a 40 amp fuse in #22 and see if that helps

Customer:

i thought so too, but the fuse slot was empty,

vwcrazynm :

is the terminals where the fuse should go you might need a flashlight to see

Customer:

i already tried that, i had fuse #40 that was a 40 amp fuse in it, tried it in its place, and nothing

vwcrazynm :

?

vwcrazynm :

okay

vwcrazynm :

it sound like you have a controller problem

vwcrazynm :

does the light on the controller come on when you turn the ac on?

Customer:

yes

Customer:

i have also check continuity in the controller and it seems to be working

vwcrazynm :

okay

vwcrazynm :

im trying to find if their is a relay for the blower also

Customer:

okay, i hope you have better luck then i did, i've searched ac relay, blower motor relay, ac fuse, i came out empty handed

vwcrazynm :

their is a resister in the blower box next to the plug for the fan motor

vwcrazynm :

that is what gives you different speeds

vwcrazynm :

if they burn up then you can lose the fan

Customer:

in order to get to the resister, do i need too remove the blower motor?

vwcrazynm :

no

Customer:

let me see if i can reach it, i'll tAKE MY LABTOP WITH ME

Customer:

sorry about the caps

vwcrazynm :

it is right next to the blower motor plug should have two screws that hold it into the box

Customer:

-

Customer:

10-4

Customer:

i'm not seeing anything with 2 screws

vwcrazynm :

should have at least four wires

Customer:

i see something with 4wire, but it looks like thats going to the cabin air filter

vwcrazynm :

that might be it

vwcrazynm :

they have it mounted to the box be not for any reason so it can be anywhere

Customer:

its a long black looks like a female connector with 4 wire coming out the back of it

vwcrazynm :

yes

Customer:

how can i test it, i have a fluke meter, i'm an electrician, but i dont know car electrocnics

vwcrazynm :

let me double check one second please

vwcrazynm :

should be able to ohm read it because it is a resister should have different reading on different pins

vwcrazynm :

alldatapro isent showing a test

Customer:

what should my ohm readings be

Customer:

i dont think i found it, i turned my car on and with the connector disconnected and the fan started workning, and it also works with in plugged in, i dont know why it only works when it wants to

Customer:

spoke too soon, its not working again

vwcrazynm :

?

vwcrazynm :

do you have the glove box out

vwcrazynm :

?

Customer:

give me a minute and it will be

vwcrazynm :

sure

Customer:

i got it

Customer:

still there

vwcrazynm :

it should be slightly towards the drivers side of the blower plug

Customer:

i see a small rubber hose

vwcrazynm :

no plug?

Customer:

there is 4 plugs and 5 terminals

vwcrazynm :

?

Customer:

on of the pugs is beige and the other 3 are black

vwcrazynm :

four different plugs?

vwcrazynm :

it should be black

Customer:

correct

vwcrazynm :

do you see anything screwed to the box?

Customer:

not that i can see

vwcrazynm :

okay

vwcrazynm :

the picture they show it right next to the blower motor plug in the box

vwcrazynm :

Full Size Image
i dont know if you can see this pic but thats the location

Customer:

can you email it to me***@******.***

vwcrazynm :

no it wont let me see your email

Customer:

for whatever reason i can see the picture

Customer:

cant see the picture

Customer:

i found it

vwcrazynm :

i think it only has one screw

Customer:

no screws, i'm reading continuity from prong to prong across all 4 prongs

vwcrazynm :

okay

Customer:

does that mean its good?

vwcrazynm :

read ohms

Customer:

on the resistor?

vwcrazynm :

yes

Customer:

from prong 1 to 2=

Customer:

1.3

Customer:

from 1 to 3=1.9

Customer:

from 1 to 4 =0.6

vwcrazynm :

by the reading it seams bad

Customer:

from 2 to 3=0.6

Customer:

can i pick this part up at an outo parts store?

vwcrazynm :

probable not

vwcrazynm :

dealer only

vwcrazynm :

but worth a try

Customer:

damn it, can you give me a ballpark figure on how much i'm lookling at

vwcrazynm :

let me check

vwcrazynm :

part should not be more than 50$

Customer:

thank you for your time

vwcrazynm :

thank you and if their is anything else i can help you with please let me know

Customer:
