I have a 2005 Bonny GXP and have replaced the blower motor.
It is located under the dash, passenger side, just above the passenger toes.
It's easy to replace, and the cost of the blower has come down a lot!

Basically, remove the kick panel under the dash. Unplug the blower. Remove the vent hose. remove the three screws holding the fan, and it will drop out.

I come across this every day with LCD Tvs.What it is, is dust between the layers of the LCD. When dust particles settle behind the front layer of the LCD, and the LCD is pressed i.e when cleaned, the layers can be pushed together, resulting in a shadowy streak. If the LCD is stripped and cleaned it will be ok.
We have the same telly and had the same problem. Ours was bought Jan 08. It can be repaired, as we had ours returned from the philips repair specialist yday, but it cost £190.
