I changed the heater core in my 2000information jeep grand cherokee. Put it back together and there is no ignition and no dash lights. I did disconnect the pcm with battery disconnected if that makes a difference. I pulled back apart to check to make sure all wires were reconnected. Put back together and still no ignition or lights. Thought maybe the ignition switch so I replaced it and still nothing. Someone help please

Did you hook the battery back up?

I know enough to hook battery back up and i rechecked all connections which were good.

Don't know what year your jeep is, but check the fuses in the panel by the glove box. (reread, 2000)
