I have encountered several issues while trying to fix my ac system. I posed here a few days ago, and found out that because of the corrosion thats why the connectors were stuck. But everything is stuck, i cant get the accumulator off the line that goes throught the firewall. I also cant get the rigid line that goes from the condensor, through the fire wall. Ive read that some cars have a special tool, but cant seem to find one for my car. also any tricks to get these things apart would be helpful.

thank you

These vehicle should have threaded fittings so normal wrenches are all that is needed. Issue most likely is corrosion. It's common on these vehicles and besides some penetrating lubricant;t not a lot can be done about it. Some try to heat up the connection or even doing the procedure lits in the tips forum. A lot of the time one connection end up being damaged and the item or items will juts have to be replaced.
