I've got a 2011 Ram, V8 5.7 Quad cab. Around 137,*** miles.
I've had it for about 4 years. Since I've had it, there hasn't been heat on the drivers side, just the passenger side. I've always assumed this was a blend air door problem.
A couple weeks ago during the cold snap I lost heat on the passenger side too.
Since then I've completely flushed all components of the coolant system, no noticeable debris, everything flowed easily, replaced thermostat, refilled with new coolant and distilled water.
And I did the HVAC reset by holding the recirc button twice.
All the hoses seemed to get hot like they should.
Heat worked great on both sides, for 2-3 days.
Now, I've lost heat again. When the truck gets up to temperature, turn blower on and it blows hot for a couple minutes, then its back to just warmish air. For a minute when the blower is turned on, there's a faint odor of antifreeze, not for long. The floor is dry, and I don't seem to be losing coolant.
My model does not have a cabin filter.
Do I have a problem with one, or more, of the blend air doors?
Looking for any input,
Thanks
