07 ES350 Heater issue
So it seems like every year I have heater issues last year it turned out that it needed a coolant because there was a bubble in the system or it was low on coolant I forget which it was
but this was not the issue I was having last year now its something different
when I started the car with my remote starter and let it warm up on one of the cold evenings so far of the winter it was still cold in the front compartment of the car and only time heat was coming out of the front vents was when I was driving and moving, however,
the rear vents always had heat never got cold no matter what. any ideas what the issue is going to be ?
the front is cold at times the rear is always heated no issues in the back.
thank you

I bet you’re low on coolant, or there’s lotta air in the system.

i just don't understand how this can be the case every year like for the past few years every winter its because its low on coolant or air in the system I just don't understand how this is possible like I had it flushed last year and the year before also it got rid of the issues until the following winter season if thats the issue.
I don't understand how come it would be a low coolant level or air in the system if it was in front and rear no heat unless driving and moving then I would understand why it's it being low coolant but I don't understand how the rear could have heat all the time no matter what
but the front doesn't have it all the time just some of the time unless I'm moving then it's usually heat most of the time so not sure how that could be it
wouldn't it both front and rear be cold if it was the issues?

Because of a small leak somewhere

but no smell of burn coolant no sense or visual scene of any leaked fluid from under the car ever unless of cours its the condensation of the ac in the hot times.
but other than that nothing
so im just a bit confused i don't get how their is a leak somewhere but no sense of it
and if i where to go and have it checked out to see if there is a leak from past expericnes even when their was not leaks the pressure test on a old car with older hoses and lines will cause a leak atleast thats whats happened to me in other vehicles before lol.
i will check the fluid in the morning and see where its at if i need to ill add a little bit just confusing and all
but other than that nothing

The leak is probably so small that you cannot detect it. The only way you can find the leak is to pressurize the cooling system.
