Question about 1998 GMC Sierra
You would have meant that the blower is not effficieent to blow the cold air well into the cabin.? If so then the blower is faulty.A clogged filter in the blower will not recirculate the air from within and will be dying down.
So get teh blower filter fitted at the intake of the blower unit to be taken out and dusted with high pressure air. This must be done periodically and and AC car is most recommended to be cleaned on the inside and not run with windows down on dirt/dusty tracks, as all the dust accumulating will clogg on to the filter and will even give a bad smell.
Also if possible clean the fan blades, the vents and also the cooling coils accordingly to your access.
I am sure this must solve the issue.
