There should not be a blockage in the lines if you flushed the system like you should have.

Did you change the accumulator?

[tom32]

yes I did with (4 season brand) my think the core under dash on passenger block some thing in there

Sorry maybe I didn't make myself clear.

You flush then entire system with solvent made for the job pushed by compressed air. Basically you do 2 points. One end of the condenser and look for the fluid and air to come out the other end.
The other point is one end of the evaporator and look for fluid and air to come out of the other end. All hoses that remain on the system get flushed at the same time you flush those 2 major components. In other words, you flush through the hoses to the condenser and through the hoses to the evaporator.

So I ask again, did you flush the system correctly?
