ac not blowing cold on driver side

[quote:e390f327a5="damien plunkett"]I have an 2003 impala with 124000 miles and 3400 engine. I recently had refrigerant added because was not getting cold it worked fine for a few weeks and then all of a sudden now it only gets cold on passenger side .I have dual climate control but it only gets hotter if i move it up but doesnt get cool at all just blows hot air can anyone help me with this problem.[/quote:e390f327a5]First you need to have the A/C system leak tested.If it has low charge,the pass side will cool but the driver side will be warm.
