#Fuse 29 - Fan
« on: 29 April 2023, 13:07:09 »
(Omega Y32 2001) (France)

Hello,

I have a problem with fuse 29 (radiator fan).
The fuse blows a few seconds after turning on the air conditioning when it is hot, or a few minutes after turning on the air conditioning when it is less hot or cold outside.
I concluded that the air conditioning fans had a problem with the air temperature. That is to say that when they are hot, the fuse blow. A I Wrong ?

Is the a relay inside of the fan ? A relay who doesn't like the heat?

Thanks for help

Aircon fans are in front of the radiator. Check both spin freely and report back  ;)

All the relays are in the relay box.  Andy B posted up a diagram for how to test various fan functions from a test socket in the relay box.

Thanks Doctor Gollum,

I know where the fans are and I know they are working.
The fuse blows after a few seconds when it is hot after several minutes when it is cold.
I know that the fuse don't blows when I don't start the air conditionned. And I know that the fuse blow when it's, so I think it is inside fan and not electrical cable but I'm Not sure, because I don't know how it is inside fan motor.

Hello The Boy,

I'm interested, do you know where I can find Andy B's diagram?

That isn't what I suggested. They might 'work' but if one is binding it will draw more current. They only switch on with air-conditioning or if the car is getting hot. You suggest that the fuse blows with air-conditioning.

With the car off, spin the fans by hand. Any tightness is a problem.

Ok I understand, I've spin the fans by hand, there is no resistance, the two fans turn identically

Back to basics, does the fuse blow with the fan disconnected.  Obviously, be cautious about engine cooling.

I disconnected the first fan.
When I turn on the air conditioning, the other fan runs intermittently at high speed.
I no longer have a blown fuse.

So, I reconnected the fan and drive for about 20 minutes with air conditioning. The fuse still hasn't blown.  ???

I dont have an Omega to check any more, but from memory:

A/C off (or A/C broken)
Front 2 fans are off, coming on slow speed when 1st temp switch hit (around 92C?), high speed when 2nd temp switch (97C?).
Slow speed fans will continue after ign switched off if 1st temp switch still activated.

A/C on (and functional)
Rearward fan on and front 2 on slow speed, front 2 high speed if 2nd temp reached
Front 2 slow speed stay on with ign off, if 1st temp switch activated


(Temps are the switch value, bear no relation to the dash, but should correlate-ish to ECU coolant temp sensor).  On V6, I seem to recall both temp switches are in the same screw-in module in the rad)


Can a v6 owner confirm my memory?

From this, further testing can be done by shorting out temp swicthes with a paperclip and a/c off, checking what happens.

Two thermoswitches in the radiator.

There's a pretty comprehensive guide to testing the fan electricals  ;)
