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. [br]
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. [br]
Both hoses on the heater core are hot, but only the driver side is even warm. What’s happening here!? [br]
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
