as above really I am not getting heat into the cabin except when I put the heating on max.... but anything I select before that i just get cold air coming thru. So can anyone tell me if thats a problem with my heater matrix or should i be looking else where?
Test the coolant system for leaks, if all is good then check flow through the heater matrix from the connections on the bulkhead.
Removing the heater matrix and heater box is a nightmare, so check everything first.
I must admit I didnt get a chance to check the coolant but will do...because as mentioned I looked for the heater matrix and realised it wasnt going to be easy to take it out just annoyed that silly problems are stopping main projects from starting
