Heater not working, blowing cold air
 

Hello,
The heater on my 113k miles 07 es350 does not seem to be working. AC still works, but when I turn on the heater, the air is ice cold. I haven't found any leaks so far, coolant at the full level, I bled the coolant too. The temperature is also normal.
Anyone has experienced this?

Only thing I've read about that might cause this is blocked heater core.
If that's the problem, have seen a a how to on Youtube by Eric the car guy:
Go to Youtube and search for: How To Unclog a Heater Core

I'd put the link here, but all that happens is a black box

This happened to me when i replaced the coolant on my Lexus, i had cool air but no heating. All you need to do is bleed the air in the system, like Riick said your heater core is clogged. To fix this first you want to place the car in a incline so air can travel from the back to the front of the car then with the radiator cap off you want to squeeze ( as many times as possible) the biggest hose you see going to the radiator, this will push air out. i first did it with the car off then with the car on. Placing the car in a incline is not required but it helps

also possible your vents are not opening

Thanks for all the help guys. It turned out that I needed to bleed more air out of the system. I also found out that the middle vents weren't blowing as hard as the other side though, any idea what that could be?

It's a good thing you found this and eliminated the trapped air in the system as this can cause all kinds of serious problems with your heads. Coolant replacement needs to be done "by the book" to avoid these issues. Most Toyotas have a bleed nipple at the uppermost part of the engine where coolant circulates. When refilling the system after draining it, this bleeder nipple should be open to allow air to escape.

Play around with your HVAC mode and defrost controls to get an idea of how they affect which vents air is directed to. You may simply be in a mode that favors the side, defrost, or bottom vents.
