Remove the hdwr holding the blend door and remove the complete bracket. You might have to compress (squeeze) the blend door rod )ends) together to get the ends out the box. Then remove the 3 screws holding the motor/cage and the mount bracket. Use a allen wrench in between the cage fins to loosen the set screw. Remove the cage off the motor shaft. Remove motor from bracket. Unless your motor came with the bracket.

Then back together as came apart. Make sure and test power up and ck that the direction of the blower motor is correct. I would NOT trust that the wire colors are 100% correct. Urban legend that some times they are wired backwards.


Just saying do not get mad at your evap box for being so big.

No this is not the way to do it either, but it can be done. There are some FTE threads about it.

Some things just happen to fit...sort of.
