Is my Ac clutch supposed to run all time when the Ac is
on max or other setting ? Compresser is working fine but
the clutch only runs for a second or two and cuts off stays
off a couple of seconds comes back on . Not enough time
to run to put cool air in car .
A/c system charge too low to maintain minimum pressure, hookup a manifold set and check the pressures, text book pressures should be 32 low side and 150 high side, but external temperatures will cause this to change, so try to check them in the coolest part of the day.
Ok thanks I put three 12oncence cans in it is that too much it should take 20lbs right do I need to let some out or just check it like you said .
Each can is 3/4 onces
Don't go by Lbs. or ounces use the pressures as your guide. Did you also add oil to the system?
