Have the above code - diagnosed as the rear evaporation hoses need replaced. What are the steps to replace these hoses or do I have to have the dealership do it? Can I buy the parts from Autozone or do I have to purchase from dealer. As for the window, the drivers side window will not work all other windows are fine. Had the front door window regulator replaced two years ago because it was doing the same. Can you provide details of how to fix this also.

 

P0455 has nothing to do with the AC, which is what you are mentioning. That code is a large Evaporative emission leak, meaning you have a large fuel vapor leak. Check all of the rubber hoses between the fuel tank and the engine. Especially at the canister in front of the fuel tank and around the air cleaner. As far as your window goes, sounds like you need another window regulator or the master switch itself is faulty.

 

May be the window switch, they have moving posts and levers inside. Take it apart, it may be gunked up with dirt.

 

na T/C has an issue with the regulator and motor assembly getting stuck u can free it up temp but will fail again. U need an assembly and they are not cheap or easy to install. Take it from a chrysler tech

 

did you get this P0455 fixed? what itwas?
thanks
