Did you replace the one in the console? or this one? look at the top of the box right side firewall There is a plug with the resistors for the speeds looks like this may have the high speed one burnt out.

Check the heater fuse. High speed is not through a resistor.

Also check the connections on that plug really good!
I've had my share of corroded plugs there on a few different vehicles!
