should a/c radiator fan show up faulty on vag com.........my climatronic is not cooling......fan don't come on.....but no faults showing

Lummox

Is the compressor cutting in at all?

not sure what you mean?everything on climatronic seems to work as normal....but cooling....the vag com shows compressor ok........pressure is 5.4 bar[assume it's gas..don't know what presure should be?]............fan not on...cooling is better when driving at speed......so i suspect fan....but how do you check?

thebloyn

Can you move the fans by hand if you try, one of mine had siezed and you could not freely spin it.
Can you hear/feel the compressor kick in? see if the revs dip at idle when its switched on somtimes you can hear the engine note change due to the load.
Oh and both fans should spin with the ac on.

edwardob

spin by hand all right.......don't spin on a/c on ......so looks like fan problem

Theresias

Year, Make, Model? Compressor Shut Off Codes?

octavia 11 1z bkc 2005...shut off code??.....after fiddling with vag com.....turning econ on it is 6....leaving it on auto it reads 0[zero]

edwardob

still problems with radiator fan
anyone know what radiator activation...9.6 % means...[on vag com]
when i manually activated [hot wired] the fans...it read 85%

Theresias

Current compressor load? How many Nm?

i think it was 1.3....but i'll check it again

fordfan

Silly question, have you checked the fuses?

edwardob

the ones i know i did!

edwardob

here's read out today.....compressor load goes down with increased revs
12:37:54
0.0 Compressor Shut-Off Code
800 /min Engine Speed
01:06 Standing Time
0.825 A Compressor Current (actual)
2.3 Nm Compressor Load
6.6 bar Coolant Pressure
9.6 % Radiator Fan Activation (actual)
0.0 % Radiator Fan Activation (spec.)
OFF Engine Speed (increase)
25.5°C Fresh Air Intake Temperature
28.0°C Evaporator Temperature

Theresias

Most likely a new compressor needed.

thanks.......but the truth is painful.......

anyone out there with climatronic that would do a readout on their vag com for me

just curious as to what the readouts shoud be like...
espeicially compressor load.....coolant pressure
radiator fan activation


please on near the end of searching

Theresias

The problem is known, we get at least two or three per week at the moment. Other than these values all detailed checks do require mechanical steps...

so are my readouts normal on vag com..........??
anyone know how to check slow fan speed on 2005 octavia?
i can get the high speed working by removing sensor on bottom of radiator...but no idea how to test slow fan speed..
[the older models apparently had three wire in same place and you could just bridge them out..but not on new octavia.only 2 wires which turn on high speed once removed]

Theresias

Again, your problem is the compressor - not the fan.

Maybe so...but i'd like to know if the fan [slow speed] is working
maybe someone out there knows how i can test it

bornlucky

the air con pressure of 6 bar suggests the system is idle, suggest you test the compressor supply voltage if ok the as THERESIAS said compressor is faulty.
