Little heat from driver side. Others are air temp
My mother in law bought a used Buick Lucerne 2006 a few months ago. The ac works great, the fan runs good at full strength, but I can’t get any heat except for the drivers side vent and it’s not much.
what I’ve done so far is
checked coolant level, replaced thermostat, flushed the heater core, verified actuators move each change, bled air from the system, and flushed entire coolant system.
Both hoses on the heater core are hot, but only the driver side is even warm. What’s happening here!?
Also I’ve been having to add a little antifreeze each time I test it, but I’m not getting drips or anything like it’s leaking out
