Failure of power windows, door locks, radio, and climate control at same time on Chevrolet Trailblazer
5 people shared problem details
It was a multi system electrical failure of the power windows, power door locks, radio, and climate control system. It was intermediate, which lead me to believe it had to be a connection problem. After internet investigation I was lead to believe it was the 125 amp fuse under the hood on the outside of the fuse box. I was in the process of jumping the fuse when I noticed a loose nut on the positive side of the fuse connector. I tightened the nut and the problem was solved. I wonder how long it would of took a dealer and how many parts to solve this issue of a loose nut.
All gauges stopped working but car still drove. This past year it stalled out and has never been the same, it's inoperable. None of the inside electrical works. If you try to start the key gets stuck, you have to jump start and even when it's jump started. If you drive up a hill or make a sharp turn, the engine shuts off. This is dangerous and should be under recall!

I also have the same issue with the power windows, door locks and climate control. The windows go up and down on their own and when this happens, my lights will start fluttering. Half of the lights are out on the climate control area. If GM knows this is an issue (there is a recall on vehicles 2006 and newer) they should be including the 2005 model as well.

Radio, power windows, heated seats, and various gauges all stopped working at once while driving. Thanks to poster Mam's comments replaced the 125 fuse....all back up and working! This form and the $7 part on Amazon saved me hundreds in repair costs! Thanks!
