This is an extremely hard task to do as the dash has to be removed from the vehicle and the HVAC case has to be removed as well so it will require an a/c recovery machine which you have to certified to have.

Na Na Na, the heater motor can be removed from under the extreme right dash!

 

But the question is: how does one remove the 5th retAINING screw from the bottom cover that is way up behind the cover? The front 4 are easy, but while the 5th can be seen with a mirrow, it's seems impossible to engage it with a socket ,even on the end of a flex extension. I've read the best thing to do is to pry down onthe cove until the plastic cover tab that the 5th srew fastens just breaks away.

 

Savy?

Ok well i dont like telling people that cause they think you are crazy when you say break the old one. yes you can but you run a big risk on breaking the heater case. his is another way of accessing that screw. The screw at the front that goes in from the top can be removed from the top by removing the dash cover and the right speaker. You can get an extension and a 5/16" flex socket down there to remove the bolt. You have to use a bright light and kind of look down through the windshield to see it but you can do it. Then to get the blower out you may have to use a pry bar and pry the dash out just a bit to sneak it out

Na, Na, Na, this answer is of no help. The problem fastener is in far front, that is, behind the cover against the floor/firewall, and it needs to be removed from the bottom not the top, not the top. By removing the floor matts and the floor insulation, it IS barely seen in a small mirror and maybe accessible with a flex drive. I'll keep try to engage that screw. In any case, your answers are NOT accepted.

 

Thanks anyway,

I have never been able to do this without breaking that retaining tab off. I would never recommend doing that though.......but has been done. It is true that the proper way of doing it is to remove the heater box from the firewall. Let me know how this goes. Good luck
