Heater blowing cold air

I realize I'm replying to a thread from 5 yrs ago but I wanted to ask if this problem was causing overheating? I just noticed the "hampster wheel" noise last week and then I overheated yesterday. I turned my climate control off and on and then turned on heat to HI and the engine temp went down enough to get home (5 min.) I'm just wondering if you all on this thread were more interested in heat and AC for cabin temp or engine temp? Thanks

oh I thought you meant hamster wheel like as in maybe a water pump. That sounds like it may be a bad blend door motor maybe? I had to replace the two of mine on under the glove box, and the relay that's behind the heater core tube. The only actuator I did not change was the recirc one that's above the glove box area

OK, this is what I'm trying to narrow down. Would a bad blend door motor cause overheating? The noise sounds exactly like a vent or a damper opening or closing. Thanks

But the engine overheat is not caused by the cabin heater.
