I drove this afternoon, and passing over a speed bump (a bump), the fuse blew. I replaced it and disconnected the plug of the first front fan. Going back over a speed bump, the fuse blew. I renewed the operation on another bump and the fuse blown. I conclude that the first fan is not necessarily the cause and that during a shock (a bump) something happens causing the failure. Could a bad plug contact be the cause? Is this a reliable lead?

When the air conditioning is OFF, no fan operates. When the temperature reaches 92 degrees, only the 2 front fans operate at low speed. At almost 100 degrees second gear engages and so does the rear fan. This even if fuse 29 is blown.

When the air conditioning is ON and the fuse is not blown, the front fans operate at low speed. and in second gear if the temperature approaches 100 degrees.

Ultimately, if fuse 29 blows, the fans operate when triggered
 temperatures but the air conditioning does not work.

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

Yes ! the fuse blew even if i disconnected the first fan, but not imediatly

Your fans aren't working properly and you have a wiring fault.

Haynes wiring diagram and the fans guide will direct you through diagnosis.

Trying to do it remotely is akin to pissing uphill into the wind.

Indeed, a remote diagnosis is not simple. I appeal to people who know the Omega because Opel has not found.

Could fuse 29 be linked to the air conditioning compressor, which could have a fault?

Follow the guide for testing the fans.

This process will identify the source of the problem. Or stop driving over bumps.

Er, no.

That's to say the aircon compressor may well be faulty, but it is a mechanical component not an electrical one.

Not the compressor's magnetic clutch?

I'm away, and not got access to wiring diagrams.

You can always unplug the compressor (single connector, from memory, underneath it, and see if that stops it blowing.

The fuse blows going over bumps. Not a mechanical problem. And certainly not one caused by the compressor clutch.

Start with the basics.

The fans don't work properly.

Not going to repeat it a fourth time. Follow the guide to test the fans and trace the wiring using the Haynes wiring diagram testing the wiring as you go.

I think the fans are a red herring. F29 does not power any of the fans directly. F29 provides the power to the coils of the relays which then turn the fans on and off. So if F29 blows then the fans won't work, because the relays won't turn on. But it won't be the fans that are blowing the fuse - because other fuses (F52) are used in the switch terminals to the fans. Power to the fans themselves does not pass through F29.

Unfortunatly F29 powers a load of things. The circuits suggest it powers CSR[1329], MK[2206], MK[2305], SH[3708], MCO[3047], IRL[1404] and AB[2649].

My bet would be SH[3705]. This is the front seat heating. It seems F29 provides power to the dashboard seat heating switches S30 and S55. From there there are connections to K183 and K184 which are the front left and front right seat heating controllers.

I had a load of problems with fuse F15 blowing. After much grief it turned out that when some lardy arsed driver moved slightly (over a speed bump for instance) it would somehow short out the seat heating, causing the fuse to blow. In my case it was F15, but both F15 and F29 feed the seat heating controllers so its possible what you are getting is similar.

The simple test is to pull out both dashboard seat heating controls (the knobs). That will disconnect F29 from the seat heating controllers. If F29 then stops blowing then it's fairly conclusive that the heated seats are your issue too.

You might be onto something, however...

The fans aren't working correctly so there is an issue there that needs addressing  ;)
