2008 Infiniti ex35
105,000 miles
Had radiator failure, replaced and bleed out air.
No heat after replacement.
Drained and replaced thermostat, suspected stuck open.
No heat after replacement and bleed out air.
Vehicle runs fine.
Just blows cool air when temp set to 90, all control speeds low to high work.
Thought on next steps...
Thanks

Re: 2008 ex35, no heat inside cabin
If you're sure you bled out all the air, there might be something keeping the coolant from circulating through the heater core. Either there's some kind of blockage in the coolant lines somewhere near the heater core that requires a full flush; or there might be a failure with the valve that controls the coolant flow to the heater core in which it got stuck closed. Those are my best guesses.

I haven't went through the check list yet.
However, my daughter just found that the passenger front side floor board is totally soaked. It appeared to be water, didn't smell like antifreeze, but that didn't make since to me either.
I just took a look at what the wet vac sucked off the floorboard, and doesn't appear to be antifreeze or having any smell. I do know that under the hood, I notice bunches of crap (leaves) that would definitely get in the way of drainage that might be taking place. We just had good rain yesterday.
I don't want to assume that the floorboard leak and the no heat issue are related, but still suspect there is a connection, even though not anti-freeze best I can tell. Anti-Freeze was down some, but I hadn't checked it since bleeding a few days ago and after she has driven a bit, so I expected it to be down a little. The liquid in the wet vac was dirty liquid, no smell, whatever it was.
Tomorrow, I will get it in garage and see what I can see.
Appreciate any feedback anyone may have.
