Cold Air

[Chris19741974]

Hi all! 
my Toyota Alphard 2006 only blows cold air into the cockpit! What should I try first to sort this out? Many thanks chris

Hi Chris, Check your header tank (the rad system one) and see if its low, bring your van up to temp (with the rad cap off) then sqeeze the pip going into the header and see if you get air bubbles.

Air vent servo went on my old ANH10, you could hear it making noises behind the dash.. small motor that opens and closes hot and cold vents.. heard this happen a few times. i think access was from passenger side ( from what i remember) then behind the dash. You can see it with a torch

Been a long time ago, so a bit vague on the memory

another one could be similar to what Alex said and could be the Thermostat not opening

I have been hearing a funny noise from behind the dashboard definitely a motor noise thanks buddy

i used to get this dull contantcreaking sound, its where the servo was trying to push the vent open but either trapped or servo was weak.

Also i think it went away when i turned off the air circulation or put the car in cold.
