well the problem is that what i see under my dash looks just like the non AC motor, but i do have AC. now that i look back at the manual it shows a motor without the vent hole and calls it regular. i guess the motor with the vent hole is heavy duty, but seeing as i dont have that type of motor in now and therefore dont have the vent hose, then how would i connect the vent on the heavy duty motor, where would i connect it.

well im going to replace my heater core this coming monday. i have factory AC and also figured id replace my blower motor. problem is the motor the parts house gave me, and the only one i can find, is the one with the vent hole, mine doesnt have the vent hole, or hose, and mine is quite a bit longer then the replacement. the closest one i can find to mine is the motor for = without AC. i believe that the motor with the vent hole is to give added cooling to the blower motor. i cant figue out why my motor is like the motor without the hole, and is longer, than the AC motor. it looks like mine is the factory motor. im worried if i change to the non vented motor it might burn up in the summer with the AC running here in 120 degree temps outside. one place told me to just keep the motor i have, after all its working fine. its just such a big job to change the core i figured kill two bird with one stone. anyone else come across this.
