A/C airflow drops when accelerating or going up a hill
I have a 96 Bonneville that needs some A/C work.
Seems that when you are at highway speed and accelerate or go up grade the airflow through the A/C vents drops to almost nothing... then pics up again when you slow down or level out.
This is really annoying... A/C shops say they can't find anything wrong.
It never did this when it was new. I have replaced the compressor and other items that have failed, and it goes into the shop soon to get the orifice tube unplugged and the system recharged because its blowing warm air.
Any suggestions about the disappearing airflow?
And why does the orifice tube get clogged so often?
