Front Heat
Hello all new to the thread,
Front heat blows Luke warm at best on driver/passenger side with controls at 90.I do feel temp change when I lower temp. and the air blows out stronger at a lower temp. Rear heat works excellent. Any ideas in which direction to go would be great I have tried and checked a few things so far

It's a 2006 escalade esv. I did check both supply and return heater hoses both are hot.i haven't checked coolant level in radiator itself only in reservoir if it was low wouldn't the rear heat be having same problem?

I also watched the actuator motor for driver side temp control change position as I lowered and raised temp and also removed actuator and manually opened and closed door still never got hot air

low coolant not always rear heater core is lower in relation to front. Will it blow hot out of any duct? Did you hear / feel door stop as you moved it from hot to cold? With dual zone there should be 2 air mix actuators ( L & R). Before I pull dash to check air doors and heater case I would back flush heater core to see if it was restricted.

Ok so I back flushed heater core and to no avail Heat was still Luke warm so I pulled the hvac fuse to do a reset,as I've read some guys have done on this forum and now the heat is blowing very hot so I'm assuming I have an electrical issue??? Let's see how long the heat lasts
