Aircon/blower Not Working Properly

[mrlukefulton]

SO I was driving around and my aircon and blower was working fine and u can switch it from feet blower, to wind screen, to normal face blower,

But now when I start my car the button for the windscreen blower flasher for like 30 secs then it allows me to turn the blower but only for the windscreen, not anything else, it I can press the buttons to change it to a different setting but it still only blows on the windscreen, you can hear the fan blowing like normal but its like the switch over thingy bob is not switching over, any reason why? any help would be great.

Thanks guys.

The air flow direction is normally controlled by servo motor controlled flaps so it may be one of these that has failed.

You mention the light fllashes for 30 seconds this may indicate a fault code is present which should be OBDII readable.

Might be worth disconnecting the Battery for a few minutes to see if the system resets but be aware of things like radio codes and electric windows which may need reseting afterwards.

Thanks for the reply, I unplugged the Battery all day whilst at work, and unfortunately no change, is there away to check the servo? where is it? and if it is the servo is it expensive? cheers.

Luke - I have just found a problem with the cigarette lighter on mine - its not working - I have looked through the web and found that its a common problem in the states where by the fuse blows on the lighter and this is also on the air con circuit so it may be the fuse.

I know it may not be the same for the UK cars but an easy check - see if your cigarette lighter is working - if not check the fuse for it as it may be as simple as a blown fuse..

Interesting. Il check the fuses tomorrow. The cigarette lighter fuse box is under the steering wheel. I've tapped off the fuse box for my satnav and mates phone so it's all wired up behind the dash. So It might be just a bit 2 much power being drawn. Thanks. Will update when I've tried it.

So checked all fuses and nothing, all is running as it should. I'm guna see if I can get it plugged in tomoz. Steve2006 where is the servo? Is it swappable?

the servo for my 2008 is250 is behind the glove box, 2 servos one for the recirculate flap and the other for the centre flap
