QuestionHi. Several days ago my 2004 durango air stopped blowing cold. it blows on all speeds at the normal rate but not cold at all. seems as though only the fan is running. could you please help>
AnswerHi Kelika,
Most times, this is a low refrigerant condition in your A/C system. In order to prevent damage to components, the logic shuts down operation if the refrigerant pressure is below a certain value. Have a certified shop diagnose the A/C system.
The reason I say diagnose: these systems are pretty complex, particularly if it's automatic A/C, and there's varying reasons why it can stop blowing cold air. It can be an electrical issue (poor connections, faulty electronics), a mechanical condition (linkage disconnected, etc) -- to name a few. Also, the possibility of a Technical Service Bulletin (TSB) that addresses this issue as well -- depending on your build date and engine code, I see one TSB with an Expansion Valve problem.
Most times, however, it is a refrigerant leak, and the normal fee for a charge and leak test is approximately $75-125. Normally, this includes an R-134a charge, an electronic leak test, and if necessary, a dye. Sometimes, the dye is not checked for until the system leaks enough to stop -- if it's a small leak (sometimes it takes a couple of weeks). However, it can be verified with a black light, and repaired properly.
Good luck!
