I had to unplug my battery for about 4 hours due to the blower motor not shutting off. I fixed the resistor but when I plugged my battery back in I had no radio and no climate control. Do both of these lock out after not having power to them for some time? Or is there another issue I need to look at. I have tried to replace the climate control and nothing changed. I have lights now on my climate control box but no temp and it will not fluctuate the temp. I have no power what so ever to the radio in the front (boss theater radio) nor do I have it to the backseat controls for the radio or the heater. Please help I am at my ends wit and am running out of ideas and money. I have checked the fuses as well all are good. Any suggestions?

The bcm controls all these functions. Try removing the cable again and see what happens

You may end up replacing the bcm.
