Random heater issue

Post by 406Iain »

Hello chaps.Hope we are all doing well.
I have a new issue hurrah.
On the way to work at 6am the other morning I fancied some warm air so i dialled in 21degc on the climate and turned up the fan.Lovely,for about 1 minute then it went cold.Poo,22 hot,1 min cold.The same all the way to 29,now at 30 its hot and stays hot.
So what the hell is the problem??
Coolant lev is fine,engine temp is bob on the middle of the guage,no over heating or coolant whiffs.Im confused.
Its been to a garage and had the system pressure tested the stat checked and nada.Can anyone help out with this as im kind of getting the feeling Ill need to take a trip with my bank manager to my local Peugeot dealership.
Thanks for any input.
