ok now, I have the dash pulled and I am in the box where the heater core is located. I am trying to get to the blend door motor, but it is on the bottom of the heatercore housing box. I am stuck and don't know where to go from here. Do I have to take the entire housing out, which means unhooking the heater and evaporator core? If so how do I do this? I have been looking for screws or bolts or something, but I am completely lost. PLEASE HELP!!!
