Hi everyone! First off, I have scoured the threads for help on my issue. However, not one thread/post fits my issue enough to think its what I need to do. Also, I think I may have more than one issue. :-/

First thing, I was thinking my AC clutch has too much gap and was gonna do the "fix it" listed in another thread. However, my clutch wouldn't engage like it states needs to be done. The only time my AC blows cold is when it's cold/cooler outside OR I rev up the RPM's but it hardly stays engaged. I had a friend do a few diagnostics on it, with a paper clip (assuming he did it right) he feels my clutch is bad. But I've read the clutch is either good or bad, works or doesn't work, no in between.

Next, it doesn't seem to blow as hard as it used to. I replaced the blower motor last summer, but even before that, it seemed to not blow very hard. If I have it on low, it's very hard to feel it. With a crew cab and 2 little boys seated in the back, they often end up sweaty and miserable, no matter how far we go. :-/ I've read the orifice tube might need to be replaced, or something needs to be cleaned cuz it's dirty or clogged like the orifice tube. But I can't remember what.

Thank you all in advance!!!!

Check clutch gap. See HVAC faqs.

Diminished volume of airflow is usually caused by a buildup of dirt and dust in the fins of the evaporator core inside the dash plenum unless the vehicle has been retrofitted with a cabin air filter. Usually, you can remove the blower motor for inspection and some cleaning.
