Default Speedo & Tach jumping when engine is turned off.

Hello all. I am new here, so please excuse if this has been asked before.

I have an 02 PT Cruiser, the battery is constantly going out on it. I know I have replaced one at least 6 times since I bought the car new. The battery is out again, but this time the speedo and tach are jumping and making a ticking sound even when the ignition is not on and the key removed. Any ideas on this one? And what could be draining the battery. This car has been in the shop more than I care to be.

Either you have a short in the wiring, or your ignition switch is going.
Have you had the cahrging system tested? Lots of places do it free. Your alternator could have lost a diode, or your multi-funcion switch could be bad - draining the battery.
