Chevrolet Trailblazer No Electrical Power to Interior of Vehicle

(19 reports)

Electrical power may be lost to the interior of the vehicle due to a blown 125 amp fuse located at the under hood fuse box. This fuse can blow if jumper cables are connected incorrectly. Replacing the blown fuse will commonly correct this problem.

Lost all power to locks, windows, mirrors, interior lights and radio don't work. Message recorder and garage door opener also quit working. -
Passenger side of the vehichle, interior lighting (Radio, overhead, mirror, and power lock stopped working) -
During the summer I would hear what sounded like something trying to start up under the driver side and I could feel a vibration on the driver side floor. So, I looked it up on the internet and found out it was the secondary air pump. After changing the air pump & the air pump switch no crank, no start, battery drain, back wiper, door locks, front windows, seat heaters , the front dome lights and radio stopped working. Purchased a new battery change the starter & the mega fuse. Started pulling out the fuse one at a time to find out what was draining the battery. Purchased a ignition switch from Advance Auto still nothing after a month I called my mechanic he tried to start my truck and found out the key was not turning all the way up. He said the ignition switches sold at auto part store would not work I returned it and got one from Amazon.com he told me to make sure the switch is lined up with what looks like a little white pole or button that you can push in with your hand. He took the old switch and turned the wheel that is on top back a little and the truck started. when I got the new switch I put that in and now my battery is not drained the truck starts the wiper, power locks & windows, lights work. The only thing that is not working is my touch screen radio that worked fine with no problems. The bad switch killed my radio -
Both rear bulbs stopped working at the same time. When I signal they work and my hazard lights work -
I replaced the 125 amp still have no power in rear -
