i have 2005 Dodge Caravan that has been acting wierd lately. when i start the van up, the speedometer will go all the way to 120 and back to zero after 4 secs. my radio periodically turns on and shuts off right after. and when i shut the van down, everything inside the van (heater, lights, ect.) will turn off 4 to 5 secs after. my dad thought it was the battery and it had about 5 pounds of corrosion on it. cleaned both terminals and still, same thing happened.

im thinking it could be somthing wrong with the computer, by i dont want to spend so much money on a computer

your help is appreciated:)
