    What do you turn on when this happens? Defroster?

    Was thinking compressor might be locked up. When the defroster is turned on the compressor also comes on. If your controls are bad during the other settings the compressor might be triggered as well. Should be no other reason for you to lose engine power with heater function. Sorry if I didn't help. If I was close I would check it for you. Need to have someone check it.
