So i bought a blower motor/heater ac fan. from autozone. my question is do i need the bottom cover that has the little plastic hose attached to it cause it wont fit on the new motor from autozone. i will try and get a pic up later so you can see what im talking about, but its the cover you have to take off to get the blower motor out there is a plastic hose hooked up to it.

 

Here is some pics the first one is the cover im talking about and the 2nd one is the gap that the new blower motor leaves when its in the cover.
is there a porpous for the cover? since it has a plastic hose attached to it

 

Didn't the one from autozone come with it's own cover that is only slightly different from the OEM unit?? If so, don't use both covers.

 

No it didnt come with a cover.
