My dash cluster isn't working. theres also a draw on the battery.

Check the power outlet (cig lighter) fuse first... See owners manual.

You have whats called a parasitic current draw which means that one or multiple circuits are not going to sleep while the car is off. A scan tool is not going to help you here. This requires some equipment in order to diagnose. I recommend you take the vehicle to a trusted repair facility. In order to diagnose this the car properly, it will have to sit undisturbed in order for all the modules to go to sleep. usually take about 30 minutes, but can sometimes take longer. I like to use a low amp probe and an oscilliscope for these.
