No hot air
#1
Hi all.
I'm hoping this is not what I think it is as I know how big the job will be but I have been struggling to get heat though my vents. There is a very slight heat but not much.
I have tried bleeding and I can't get it sorted. There is no leaks from what i can see on both footwells.
I have tried flushing and there is water passing both ways.
Any help and knowledge would be greatly appreciated

If the flow & return from the heater core are hot (check from within engine bay) & you've got no coolant leaking inside the car then I'd say the core is fine (not blocked). If you're using a 50:50 mix of glycol & water then even with a slight leak I think you'd smell it in the car. I know that from experience.

Flow and return are both hot(flow hotter than return) no leak from inside. Tried bleeding it to death to no avail

If you're using some sort of header tank to bleed the system you shouldn't have any problem filling it without air locks. I wonder if your issue is with the heater controls themselves.
