    1995 Audi 90 V6 12V Heating Core doesnt heat up

    Hi!

    I just replaced a 1995 Audi 90 V6 12V Heating Core and still have no heat and hence the dash is still out.

    Initially I though it was a blocked heater core but it is not. Two heater cores are both not heating up and this seems to be a flow problem.

    The flaps have good seals and rotate fine. The heater core is bled and air is out. However, the heater hoses do not heat up well.

    What's keeping the heater hoses from getting hot and how do I fix it?

    Thank you!
