Default My Max AC quit working

As the title says... my max AC quit working, ie, when I put it on max nothing changes (like it used to). It's just the same as normal AC. It still cools, but the volume of air doesn't kick up like before.

My car used to just about freeze me out when the max AC was working correctly... what gives? Anyone?

Thanks in advance!

(btw... it's an 88)

Probably your high fan relay, it's located directly under the fan motor.

Okay, thanks I'll check it out. Thought maybe it was a vacuum problem or something (doesn't the venting system operate on vacuum?) Hope it's just the relay, that sounds like an easy fix.

It's a C4. There is no easy fix.
