Heater Motor Problem

[delboy1]

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.

Welcome to the forum.

 

Possibly

- there is a problem with the air direction flaps or motors that move them so you can not direct the air over the windscreen.

- The drain from the air con could also be blocked so that water builds up in the heater box - with the air con running you should see drips of water under the car from the drain if it is not blocked.

- If the anti freeze level is dropping there could be a leak in the cabin heater matrix - if so you would also notice a smell in the car a bit like burnt curry.

- inside the car is damp due to rain getting in - check the carpets and under them, also in the boot, for water ingress.
