I replaced the blower motor according to a TSB. That was easy, but after replacing it, the Recirc light flashes a steady on/off code and I can only get hot air. When I turn the temperature control knob to its coldest setting, I can hear some sort of vent close, then it blows as hot as it gets. I looked under the dash on the driver's side and I can see some sort of cam turning to close this vent. If I turn the temperature control to full hot (all the way to the right), the air temp drops, but it's still warm. Whatever vent that is isn't closing all the way. I've seen other threads where this had to do with an actuator and some sort of loop that was supposed to be attached to it, but I don't know where to fix this. Can someone tell me what this code is or how to fix the problem?
