Hi. I'm new to this so forgive the mistakes. I have a 07 plate c4 grand picasso vtr+ 1.6 hdi. When i bought it the heater would only blow in the back. i was told to clear the traps in the inner wings but this had no effect. Now the weather is wet ish the windscreen fogs up as soon as i get in. The car has the digital screens on both sides for the climate control. Thanks in advance for any help or advice.
