A/C Blower and temperature

[Scott E. Gilman]

My 1991 200 20 v  a/c does not work well.  The system was inspected, charged 
and given the ok by two local shops but the blower puts out minimal air and 
the coldest setting is not a match for Houston's heat.  Any suggestions on 
finding a more powerful blower and making it possible to have "cold" air 
pushed out rather than just cool air?  Much obliged, Still hot and humid in 
Houston.  And yes, I've thought of moving to a cooler climate but not 
possible now. Thanks.
