i really only have the heated seat now on setting no3 till the seat gets hot
then i turn it down to no2 or off as leaving it on setting no3 all the time will only lead to problems
on the astra j before i did the fix i am sure the problem starts with excessive use of setting no3 on constant or for long periods of time
then the heater pad just over heats as rusty says there seems to be no heater pad temp control at all on setting no3
i had no problems after the fix at all but i did alter how i use the heater controls as well
and i still do with the insignia setting no3 to get the seat hot then turn it down to setting no2
or setting no1 this should prolong the life of the heater pads.
