Contaminated AC Lines

I found out that my A/C Line are contaminated. I have bough ever except the lines that go under the dashboard.
I was wondering if I could just flush those lines and replace everthing else including the condenser, or should I just take out the who dash, and replace that too.
I could borrow a CR-V for the weekend if I decide to take the dash apart on Saturday so that my uncle can come over on Monday to help me replace the whole a/c system.

You don't say what the lines are contaminated with. There are no under dash lines, just the evaporator that I know of. The lines I have seen cause problems are the ones running along the wheel well shield on the passenger side. The only lines you should have to replace would be the ones that have rusted through or are leaking and the accumulator and possibly the condensor if it has been damaged. The evaporator too, may be a problem, but I would surely test the system before going after that. A good flush and a draw down should make the system as good as new unless there is something you're not including in your post. Much luck.

Well the thing with the a/c system was that when I changed a hose and the compressor I notice some black oil coming out of it. It was the line that has a small bottle that leads to the condenser. Well, I didn't pay attention to it and when I fired up the car and started to charge it with 134a, the compressor went nuts and started to spark up.
So I took back the compressor and about everything else so that I can replace the whole a/c line. I have the condencer, and two more lines already bought. I also have the 134a and oil. And since I will have to take out the radiator to change the condenser I have bought some extra tranny fluid and anti-freeze.
I thought that there was something inside of the car where the blower is at.
Thanks for the much luck. I need the a/c for this Texas heat.

The only thing in the passenger compartment, as far as I know, is the evaporator, a miniature radiator type unit. It is located in the same area as the heater core and should not be a problem if you flush the system. Don't make more work for your self. Gotcha on that Texas heat.

I really apreciate your help. Can I flush the system mysself or am I going to have to take the car to a center?

If you're putting all new parts in then the only thing you'd have to consider flushing is the evaporator. They make a flush kit and special solvent for this. I have never done it and I don't know what is all involved. I know A/C repair is expensive but if you mess with it and goof it up you're just adding to the expense. Make sure you replace all the "O" rings with R-134 compatible ones. Keep all lines (especially the accumulator) capped until ready to install. Wish I could offer more but don't want to get you in deeper than you want to be. There are more informed people visiting here so maybe they'll offer some assistance. If you go ahead on your own, consider getting an automotive A/C repair manual. The library may have one or you should be able to purchase one for under $20.
