AC fan how hard should it blow?

Hey Guys

Just picked up a 97 C1500 the AC blows 38 degrees at the vent blower works in high speed but doesn’t seem to blow very hard is this normal for these trucks?

Thanks for any info

I would start with the under-dash components. Here's a good writeup on how to clean out the airbox:

There's no cabin filter on these trucks so whatever they suck in gets stuck in that box.
