Default Heated seats and blower motor

I have a 2017 Subaru Crosstrek with 25000 miles. So I get into my Crosstrek yesterday and the blower isnt working at all. Also, the heated seats seam to be going on and off as it wills. I take it to the subaru dealership. The dealership confirms that the blower motor is dead. They order me a new one and it will be installed tomorrow under warranty.

Here's the part Im confused about: In the Past, whenever I turn on my heated seats, they stay hot until I turn them off. In fact, I usually have to turn them off because I get tired of the heat. But this morning they seemed to be heating up, then cooling down. When I told the dealership that the seats are getting hot and cool and hot and cool on their own, they told me that the seats are "self regulating" and will do that. Does anyone know if that is the case? I swear that my experience in the past is that the seats stay HOT until I turn them off.

Any thoughts would be appreciated.

Self-regulating? Only if in the "ON" position.

If the switch is in the "OFF" position, that's not normal at all for the heated seats to have the seat heater active.

Hmmm, I interpreted Jim_Wheeler's description to say the seats were cooling and losing their heat while in the "ON" position as if the heater was intermittent.
It didn't sound to me like his seats were heating up on their own while the switch is still OFF, maybe he can clarify?

But still... if the seat heater is turned ON, in my experience the heat stays on consistently until I switch it off again. I'm not sure what the "self-regulating" feature means (implying some sort of thermostat?). They stay warm all the time from what I could tell here on my '16.

In my '14 the heated seats are constant at the low setting but seem to be thermostatically controlled on high.

From a Forester group.
Heated seats cycle off and on (merged thread)
The owners manual provides very little info on how the heated seats are supposed to operate, so I asked SOA for a better explanation. Here is the info SOA sent me:

2014 Subaru Forester
Subaru vehicles generally have an operating range of 86 degrees F to 104 degrees F. The 2014 Forester seat heaters have a different operating range. The 2014 Forester seat heaters come on at 98.6 degrees F. and shut down at 109.4 Degrees F. Depending upon conditions such as interior cabin temperature, seat fabric and thickness, these temperature ranges are target ranges and may feel or read slightly different when checked by a technician.
The system uses 7 contact points on the seat cushion and 4 contact points on the seat back to keep the system within this operating range by utilizing two thermostats located within the seat elements. They are positioned so the customer cannot feel them when seated. See the attached illustration below for thermostat locations. The switch functions are not a high and low type system like those used in previous models. When the seat heater switch is put in the high position, the elements heat up and into the operating range as fast as possible. When the switch is placed in the low position, the same amount of heat is generated but at a slower rate to reach maximum temperature. Once the maximum temperature is reached, the elements shut off until they cool below operating range then cycle back on again. The switch stays illuminated whenever the system is in use

The butt warmers work like this: high setting- they get very warm, but shut off to prevent injury (it’s in the owners manual, imagine that!) low setting- constantly on, is warm, but not nearly as warm as high setting.
TL;DR- use low setting for 24/7 butt warmness (aka- “swamp ass”
