CHEVROLET TRAILBLAZER RADIO PROBLEM
2005 Chevrolet Trailblazer • 116,054 miles
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
Ok if after i try this it still doesnt work where do i go from there ?
You may end up replacing the bcm.
Why would i have to replace that its fine
