01 lesabre blowing colder and harder on passenger than driver side

What is your question?

I have a 01 lesabre custom...I recently replaced the blower motor, actuator in glove compartment, and recharge the system...the air is blowing hard and cold on passenger but not on driver side...its blowing kinda cool like fan air but can barely feel it....can someone help?.....also need to unclog drain plug but I don't think that would stop driver side from blowing like passenger......HELP PLEASE?...

How long has your 2001 Buick LeSabre had this problem?
