Question heater gets cooler when driving

1988 528e-heater blows hot air when car is stopped, when the car is moving and the blower fan is on, the air cools off, both in the defrost and the floor mode-any ideas?

it is your heater valve. It is next to your brake master. You can get a rebuild kit for 40 dollars and it is a easy fix.
