Greetings all. I have searched and searched for any information on replacing the heater core in the f30. Currently, no heat in the cabin, have done all the necessary troubleshooting, controls, testing etc. Replaced thermostat, still no heat. I have ordered the Bentley manual, no instructions on the heater core, and have tried one other source but have yet to have that manual delivered electronically. Any help is appreciated, even to a service manual that has the information.

thanks!
