Heater Problem (corolla Tsport)

[T8TRD2009]

Hi there people hope some of you can help me?? My friend plugged my car into the obd system and my engine mngment light is on due to a problem with my heater?? It is blowing warm air when requested and it is blowing cold air when i put it on cold but when i put the heater on hot air it is only blowing warm air and not hot as it should be?? any suggestions??

hot air is only warm...

could be because its quite warm at the moment so the air doesn’t feel that warm?...

normally problems like these are due to dodgy thermostats or coolant not right.

is you car suffering low mpg as well?

no i mean its kinda weird!! In other cars if you put the hot air on its like really hot but mine is weird, as in the mpg my car is always low on juice, it loves to drink!!

Any error codes from the OBD? Could be a faulty valve in the heater unit.
