Heating playing up

[Quaser]

Hi Guys

Im having a problem with the heating in the cab (sometimes it gets a bit chilly with the hood down!)

Anyway - it gives hot and cold bursts - i have noticed that it gives off more cold air the faster the fan runs, but if i slow it down, it starts giving off hot air after a while.

I thought it may be an airlock, but i have bled the system manytimes without success!

This is driving me crazy!

Q

are the pipes that come from the engine on in the right way?
