Heater blowing warm air. Not hot.

[Sachsline]

Well as it turns out i have to drive my fwd this winter. As its getting colder, i have noticed my heater only blows warm air. Tried to source out the issue with a new radiator and hoses. New 180 degree thermostat, and new temp sensor. Still no luck. If my heater core was clogged wouldnt a symtom of that being it will blow cold air? Any other things i overlooked?

Im still without heat . No garage at the moment to flush it out. I hope it works. Ill chime back in with results.

I did do a back flush with a combination of compressed air. I now have heat. Only 2 of my vents work but its hot now and its like -17 degrees here
