Hmm,  in that case i would think blocked matrix...

Curious and just an idea but could it be a partially blocked heater matrix or even a leaking one, I didn't think non ac omega's had heater bypass valves.

Although if leaking the floor would be wet and it would smell.

Try running the garden hose through the heater pipes that go through the bulkhead, one and then the other probably find dirt will come out,  i haven't got an Omega yet but had the same problem with Our Rangey

Yup, just a stab in the dark from me, No A/C, no HBV

When you flushed through the heater matrix, did it run through easily and clearly - the the hose entering matrix being hot and one leaving cold to me means its not flowing through.... ?
