hello again,

So, I've already flushed the lines to and from the front evaporator. (and the evaporator too)
I tried flushing the lines going to and from the rear evaporator and I'm having trouble.
If I blow air into one of those lines, it comes out of the other one, but at a very high resistance.
I added about 2 oz. of ac flush and tried it again.
Now, it'll blow for a couple of seconds and just stops.
When I reverse direction, it again blows a couple of seconds and stops.
The fluid that I added never came out.
So,
I'm wondering if the rear evaporator is clogged up OR, is there something that is isolating it and blocking my efforts to flush it?????
Is there a rear orifice tube or an expansion valve that would block my efforts?
thx,
Jim
