I've got some questions about these. '95 K2500HD 6.5 TD, is there a cab
filter on these trucks? If so where is it and how do I access it? This
truck spent its whole life in Arkansas and saw sand on a regular basis, so
if there is one, then I imagine it's plugged. My air flow for the fan is
poor and it's a new OEM fan.
I've heard numerous times about some drain tube for the a/c getting plugged
and making the floor wet. Where is this and how do I access it and do I
just stick a wire into the hole to unclog it?
Last, is there a cab filter on a '93 K1500? Where and how, etc.?
