We have a 2012 Durango 325RL, and overall have had no real issues. But this one is really annoying. We're still under warranty, so guess when this trip is over, it's back to the dealer.
Ok, this is a pretty weird thing, but hoping somebody has heard of it or something close.
Our heater works great ... most of the time. The issue was thermostat ... or so I thought. It's been cool where we are at, so have the thermostat set at 63 for night. The heater comes on when it needs to. Then ... maybe on the next start up or maybe a couple later, it doesn't run. The only way I can get it to start back up is to put the thermostat switch to off and then back to on. Then it operates "normal" ... sometimes. Always starts back up, but eventually it will fault.
I thought it was the thermostat, so bought a really nice digital one. Same thing. So, it's not the thermostat. When this first happened, I included it in the list of issues we had with the unit, but the dealer obviously couldn't find anything wrong (BTW, very few issues and dealer fixed all our list, which was pretty short). I think the only way this can be duplicated is to live in it where it's pretty cool or even cold.
So, anybody have any body have any ideas. I'm thinking either the control board for the heater or the heater itself. It's a Suburban.
