No hot air - ShaneRotty - 07-11-2020
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 [emoji120]

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[emoji55]

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.
