Heat suddenly starts blowing cool air after some time
Hi - I’m at my wits end with my Toyota service repair center. We bought our 2017 Sienna in September of 2017 and in February we began to notice the heat not working properly. As it is still under warranty, we are trying to deal with the dealership garage. They haven’t been able to replicate the problem, or so they say. So after driving the van for some time, sometimes as little as 10 minutes, the heat simply stops blowing out warm air. The air coming out then feels quite cool in comparison. It doesn’t matter at this moment whether we turn the gauge to warmer or not, there is no change, just the cool feeling air. Can someone please give me an idea of what this could be causing this problem? My guess is a faulty thermostat, as it doesn’t seem to happen until the car engine reaches a certain temperature(again, my guess.) Of course the technicians literally won’t do anything because the car is under warranty and they don’t want to waste money doing anything exploratory. They can’t “replicate” the problem because they haven’t taken it for a long test drive, all they’ve done is let the car idle for over an hour. I tried to explain to the service manager that a car engine idles much cooler than when it is driven, which could be why it’s not happening in idle. I want to identify the problem and fix it, even if it’s not with the Toyota garage. Please help!
