If there is still air trapped in the heater core, that may cause it, or if it is plugged.
I hope the actuator didn't just fail on you though, they are known for doing that.

Ok, major update
I had switch computers after i had put everything back together and had had no heat. So today i hooked the orginal ecm back up and took off the glove compartment box to look at the actuator , and started the car and i have heat on the pass side again but barely any on the driver side. Is that sign that its going out or could the computer have something to do with it cause with the other ecm no heat. If you move the leave on top of it does the temp suspose to change? One heater hose is hot and the other one is warm. Honestly after having no heat in 30 degree weather a half heated car actually sounds very good right now lol

Do you have the dual climate control system?

Is your HVAC control system vacuum operated, or electric? I know on the 94 Bonneville it is vacuum, but I am not sure about the Olds 88.
I would bleed the coolant system more. Bring it up to full operating temperature and bleed it until you have a steady stream coming out.

I think his cooling system is fine now. He said his heater core hose was hot but the other one was warm. Which is an indication coolant is flowing.
That'* why I asked if he had the Auto/dual zone climate control.

Nope its not dual , from the temp gage i can tell there is jus a lil bit of air in the system. It drops down maybe 15 or so degrees after you stop and take off. Im gona bleed it a bit more but i think the problem is in the actuator or the ecm. Would moving the lever on it change the temp? Or is it inside the actuator that does the magic? Its three screws holding it on. I think i can get it off without dash removal if thats the for sure fix

ok so after driving for a few weeks and air working its way out on its on, mostly, i have come back to square one. Heat on pass side cool, luke warm air on driver side. The accuator door moves left to right when changing the temp but only pass side has luxury of warm air so would replacing it fix this issue? I was gona bleed the system cause i was having no heat now its only one side and thats the only thing coming up in my searches.
