Speedo Problems: 2001 Dodge Grand Caravan:

Greetings: 1st time user ! The above vehicle has a 3.8L and 127000 miles on the speedo. During a recent cold spell (-26 below!), I killed the battery trying to start it. It wore down to the sorry click. Click. Click. Of the solenoid. I charged the battery in the car, installed a battery blanket, and, pushed the car into the sun ! This worked and a few hours later the car started. The first time I drove it, I noticed the speedo was defective. The needle was now on the WRONG side of the stop pin at 0 mph. When the ignition is on, the needle pushes against the bottom side of the pin, approx. 7 o'clock. With the ignition off, the pin drops to the 6 o'clock position. All of the other gauges work normally: Tach, Temp, Fuel, Digital mileage read-out and trip odometer. Any ideas? Will I need a new instument cluster? Can this one be repaired? By whom? Where? Any help or advice would be greatly appreciated. Thanks, Ed in Canada. Current Temp: ~-20 below. Wind chill ~ 37 below ! Hope it warms up soon !
