It is very possible that the blower motor resistor replacement has made the blower motor rotate in the opposite direction, to fix this, you must switch the wires in the connector at the Blower Motor....

Correct, the document that I posted above states that you MUST remove each of the 2 individual wires and swap them inside the actual connector going to the blower motor...
There may be a locking mechanism on the connector that locks the terminals in place, you will need to remove the lock mechanism, then using a jeweler's screwdriver to move the locking tab over enough to remove the wire out of the connector.... let me see if I can round up a picture to show you what I mean....
Here is a pic of what I'm talking about:
Let me know if you need explanation on anything or if you have more questions...
Ok, No probem. Let me know how it goes when you can, If that doesn't fix it we can continue from there... Thanks
