Very little heat on driver’s side

I’m having an issue in preparing for winter up here in Alberta. I’m getting heat on the passenger side but only Luke warm on the drivers side. When I change the switch to demist, the temperature feels about Luke warm on all 4 vents (not as different). Hoses to the core feel the same temp both side. And when I first turn the heat on, it’s initially warm for like a few seconds and the Goes cold.

I hear the heater cores get blocked up easily, so I will be flushing that with CLR soon, I also have heard about blend door actuators being a problem?

My truck is a 2005 1500 SLT and it’s a single zone climate control.

Any past experiences or advice to help me remedy this before the winter gets here in full force?

Thanks a lot in advance!
