Air blower relay
Hi, our Passat is making problems again
The weather is quite cool, but the car is heating badly
The climatronic is switched on high
the engine temperature is right
but the cabin remains cold
No air is coming out here
The engine reaches a normal temperature
and the hoses leading to and coming from the radiator are hot, too
Thus the problem is at the climatronic itself
The climatronic has the possibilty of self-diagnosis
For the read out of the error memory we go on ignition
Press "off" and "+" together for 3 sec.
and you see the first error code 4124
The code indicates a problem with air blower
Pressing "+" you'll see the next error code
0000 stands for nor further error in the memory
To reset the memory press "off" for 3 sec - 4444 indicates the empty memory
The error code for the air blower is a little strange
From time to time the air blower is running
Sometimes the error code is in the memory, sometimes not
Such a systematics may result from a loose contact in the blower relay
We'll have a look on the relay
Unlock the cover on the upper side
and dismount the cover
This is the central electric
The relay is on position 1 at the upper left place
The relay is 106, sometime you'll find 107
Contact problems in the soldering points are common problem of youngtimers
Use two small screwdrivers to open the relay
Take the housing off
Have a sound look on the soldering points
A bad soldering point you recognize as small black line around the soldering point
Now you have the choice. Buy a new one or repair the relay by soldering it
Clean the contact with a special contact file
A contact spray may help, too
Now the relay is ready
Press the relay carefully in the socket
Insert the cover in the lower guides and fix it up
Let's try it!
After a short test, the error memory is still empty
I hope the problem is solved
The relay had bad soldering points
In a few days we'll control the error memory again
Bye, bye. Don't miss our next video!
