Hi guys. My heater blower isn't very hot. Its warm but not hot. Just wondering if anyone could tell me the temp coming from there vents on there car so i can compare.

Mines a 2002 GTI.

No engine temp issues.

Blower flap for heater is moving correctly. 

Suspicions points me towards a blocked heater matrix.

 

Thanks in advance!

If the thermostat was faulty it wouldn't open, not be permanently open? 

Fortunately they fail open; if the failed closed then the car would overheat which would be rather inconvenient.

Rechecked. 85c one side 75c the other but only 44 coming out of the vents. 

Going to check the temp flap on the heater box to see if its jammed or not going to it most warm position

They fail open, normally through thermal expansion.

Interesting. Mine failed and stayed closed.
