a/c help

i have a 1999 s10 blazer and my air conditioner doesnt blow as hard as it used to even on high it gets cold just not blowing hard can you tell where is the door to check for trash or something in it restricting the air flow:runaround:

Auto or manual controls?
Have you checked the cabin filter?
Cabin filters can get stopped up.
Does blower motor have all speeds?
