Hello all,

I have a '99 F150 4.6L. Seems I have a slight leak in the ac system somewhere. Is there an area where this model typically leaks?. Haven't driven the truck daily for a few months, does anyone think that lack of use (read lubrication circulation) has caused the o-rings to slowly bleed? Haven't really started an in-depth visual for typical signs of leak. Just wanted to check for any tips before jumping in. What are typical pressures for this system? Thanks in advance for any and all help.

like you said at the o-ring seals. look for oil by the o-rings. if there signs of oil, thats where it leaking.
