Re: Blowing hot & cold ??
I don't know if the 147 is the same as the 156 but there is a particular set of circumstances where you can have warm air to your feet and cool air to your face, could this be why you are getting a seemingly strange mix of warm and cool air?
I had a problem with my climate control directional settings about a year ago and was advised via this forum to disconnect the battery for a couple of minutes and then re-connect it again and leave the climate control system alone for a further couple of minutes. Doing this apparently lets the actuators calibrate themselves. I tried it and it worked a treat. Might be worth a try? The easiest way to do it is to disconnect the negative lead but make sure you have your radio code to hand though as you will need to enter it once you reconnect the battery.
