where is the computer located in dodge grand caravan 1995?

To answer your question it is located to between the battery and fender. To remove it: 1.Remove the air cleaner duct from the PCM. 2.Remove the battery. 3.Remove 2 module mounting screws. Remove the 14 and 60-way wiring connectors from the module and remove the module. Unless you have knowledge of vehicles don't assum its the computer you may be wasting your time and money. I't sounds as if you may have a problem with an emissions component such as catalytic converter. Again don't go and put one on the car without having it looked at first.
