Why do you turn the key in your 84 Chrysler 5th avenue all that turns on is the ac?

If turning the key in your 1984 Chrysler Fifth Avenue only activates the AC, it likely indicates an issue with the ignition system or electrical connections. The ignition switch may be faulty, preventing the engine from starting while still supplying power to accessories like the AC. Additionally, there could be a problem with the battery, starter, or related wiring. It's advisable to have a mechanic diagnose the issue for a proper fix.
