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.

Running lights dashboard radio climate control electric windows door locks stop working

Radio, climate control, power window, and door locks stopped working.

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!

No ac ,windows, no dash, no radio

No brake lights no radio power windows don't work

Key fob stopped working, had it checked, it is still good. Just won't open the door.

all stop at same time then might come back on after10 to15 min later and then anitlock will be showlng on the radio

Truck shutdown. Radio, a/c, and power windows wouldn't work. Went straight to that 125 fuse. I pulled the fuse wiped it off an reinstalled. Everything works as advertised.

I hooked a brand new battery up and started the vehicle. Nearly 30 to 45 seconds later radio power locks and windows stop with oil fuel battery and thermostat gauge. I've tried everything and can't figure it out

Vehicle loses all power, windows won't roll up, door locks won't lock, and the AC blows hot. The anti theft light is on.

climate control fan switch works in positions 1-3, nothing in 4&5. Window switch for front passenger window quit on both front panels. The radio plays but sounds very tinny and has very little volume.

Losing power to Windows ac and other things

No radio air conditioner Windows want roll up or down

The power windows and power seats and ready got a short

No power to Windows or door locks or radio
