Heat issues

[Mother nature]

I have been trying to see if my intermittent heat inside of car issues can be solved cheap and easily. I replaced the thermostat, no luck. When it does work, it is mainly on the drivers side vents. Any help is greatly appreciated!! 

Peace and kindness always,

Just some guesses. Have you checked your cabin filter critter can nest and leaves can make their way there and restrict air flow. Less air means little to no heat. 
 

Is your coolant level good, low coolant would hamper heat transfer. 
 

if those are all good then likely the heating core. Does it smell sweet when the heat is on. May just be clogged from age and you can flush it out.
