18 ram 2500 slt 6.4 heat issue

[Diskiples]

Hello. My 2018 ram 2500 6.4 slt, has good air flow and heat on passenger side. The drivers side has weak air flow and Luke warm heat, I have already flushed heater core, and checked actuator behind passenger side, glove box it’s working fine, not sure what else to do. Any ideas

It's a clogged heater core. If flushing didn't work you are going to have to replace it. Very common issue with these trucks/
