Looking for some advice/help as well as the type r we also have a 53 corsa sxi 1.2 42,000 miles as a run around, and just recently the heater is only producing luke warm air, coolent level is ok, no leaks underneath or inside car (footwells), no issues with car overheating, car seems to be running as normal.
Any ideas on what it could be ???
I was thinking Thermostat, blocked heater matrix.
Cheers Criag
