Title: Advice Needed... Climate Control
Post by: Missy_MV6 on 10 November 2007, 19:49:59
Hi Guys
Well....it had to be done we have just gone and bought ourselves another Omega MV6  8-) So have 2 sat on the drive at the mo  :y
But unlike our old one this has full leather and only 54,000 with full service history :o
My hubby drove it back and noticed that when he put the Dual Climate Control on  the "Hi" setting it blew hot he then moved it down to number 27 and it blew quite cold on our old Omega it wouldn't blow cold until it was down about 22 and below.Surley it should blow warm at about 24/25 ?
Any suggestions ?

Is the sampling fan working properly?

I don't know for sure so I maybe wrong, but I think it depends on the temperature in the car as to how much cold the climate puts in...... for instance when i am in the car I have it on HI, when my mrs gets in i turn it down to 26-27, and because it is boiling in there it puts cold air into the car to cool it to 26-27...
Hope that makes sense ::)

Hi James

Thanks

Sampling fan is behind the climate panel - it blows cabin air onto a sensor, which in turn senses the temperature of the air, so it knows how much to cool/heat the cabin dependant on temp selected.

If this isn't working, it won't sense the right temp, and won't operate properly.

Well maybe thats so...My hubby did have the car ticking over whilst inspecting the car and then he did take it out for a spin and then it was a 90min drive back in some heavy traffic.

Cheers for that ;)

If ever you're down near Nottingham, talk nicely to Mark and see if you can get a Climate software upgrade :)

Btw, nice avatar!

Is there a test for this to find out if it's actually working ?

You may be able to hear it working... but I'm not really sure, may need to pop the panel off to make sure it works

Okay my hubby will have a play tomorrow...Thanks for the help  ;)

IIRC the sampling fan is behind the little grill in the centre of the climate control panel .. place a small piece of tissue paper close to the grill ... if it is sucked towards the grill the fan is working, if it falls away the fan is not working...

I think thats the right way  :(

Fan may be OK. Sensor may be duff.

As well as the fan working, ensure the sensor is not touching anything (have to dismantle to check).

Is it a facelift, or prefacelift?

Hod on, you set to 27?, the interior is trying to cook itself so lots of hot air and interior temperature rising. Then you set it to 22, it now has to cool the interior, cold air from the vents until the interior temperature drops. Small steps and see if it settles.

It's a pre-facelift  :)

Initially he set the temp to "Hi" and then after a bit he wanted to just have the cabin warm and so dropped it to 27 and it started to blow cold rather than the warm air he thought it would.
He thought it shouldn't blow cold air until it was down to around 22

It'll do whatever is necessary to get the cabin to the temp you select, be that blow cold air or hot.... however low will just blow cold air continuously and high will blow hot air continuously.

prefacelift mv6 (being either a 98 or 99 year) does not benefit from a climate upgrade

Dont want to start a new topic so ill ask here:
1) Does 2002 Omega 2,5 DTI will benefit from c/c upgrade?
2) Same about engine and gear box ECU (it has 5 speed auto gear box)

Thanks for all the info guys.......A friend of ours told us to reset the controls and hey presto we went out in the car today and the climate is working fine...Cheers for all the help  ;)

1) Yes
2) Not sure, we didn't get the 5 speed box here, so never done one.

I find the climate control on the facelifts really queer, without the 'upgrade', if changing temp the system tries to alter the climate as fast as it can so perhaps would result in cold air being blown to equalise! I do gather the revised software makes the system more 'discreet' which can only be a good thing!

Boldy, I think Mr DTM maybe a little too far away from you, I suppose see what the local dealership say, unless of course you are arranging a 'tech 2 holiday' :)

I fixed the faulty fan on my (pre-facelift) climate at the weekend using a 1inch 12V computer fan.....it now works very well.
