Has anyone else got slow blowers?
I go out to my frost covered Omega most mornings and once the temperature needle starts climbing direct the warm air to the windscreen.
While the fan is at full power it seems to take ages to clear the screen compared to my old Saab?

Does the aircon work?

[Pmacca2000]

Yes, no problems there just slow

Cabin filter been replaced recently?

This was the problem on my old car (saab 9-5), blower performance was greatly improved when the manky filter element, plus leaves, twigs & sweetie wrappers were removed from the cabin filter.

Boot vents behind the first aid flap clear?

Blocked heater matrix.
Mine is the same, and even after flushing it the heat output is no better than OK once it finally warms up.
I have a new matrix to fit, but didn't have time to do it before we left. Just like the NSR wheel bearing that is now rumbling when it was just moaning - that will be £25 and a couple of hours work when I get home.

As far as I know the vents are clear, not sure about the pollen filter, the cars getting hot just takes a while to warm the screen enough to do some good.

Aircon is merely one component in the climate control system... does your Aircon work?

[Pmacca2000]

Yes bud, no problems with that

I would check the filter. It's a bit of a fiddle and is a classic "just tick the box" item. I also cleaned out about a foot of leaf bits from the box under the plenum (if that's the right word). If those are deeper in yours than mine that could also restrict airflow.

I fancy that as an option purely because it would affect the rate of airflow without affecting the ac or the rate at which the car got warm.

Some heater matrixes are difficult to flush completely whilst still in place .if you cut one open you will see why. Its much better to remove to do properly and on some cars such as cav mk1 / manta this is very easy to get out but on the omega its more of an involved job.if your car hasnt been "modified" to make this easier then this isnt a 10 minute job.and if you did get it out it would probably be better to replace after all the trouble .even if the pipes are getting hot this doesnt prove you have a good flow through it but its also worth checking that your servo arms are connected to the flaps. Common problem due to them being a push fit plastic.they can come off and require heating/ bending to re fit.

If the aircon works it should demist effectively almost regardless of temperature.

Are the boot cubby holes full of stuff?
Are the rear and face vents closed when you are trying to clear the screen?
Have you tried opening the rear windows slightly to draw damp air from the cabin whilst driving?
Do you use climate control in ECO mode?

Flooded pollen filter is your most likely culprit if cabin is damp.

My money is one either aircon not working, being misused or a blocked scuttle.

There is a guide, in the relevant section.

Model year is it?

There was an issue on some early Facelifts where the recirc would kick in and you had to cycle through the settings to get it to reset
