Driver side speaker is the only one that works in my 98 s-10 blazer

well, the first thing is to check the fuses and or relay for power windows.should be listed in your owners manual. if ok, then remove switch from drivers side window and check for power. if power to the switch then use a jumper wire from power side to motor side of switch. if window works then its the switch causing the problem. Good-day!

Have you tried unlocking them from the driver side control?

Hello, I am assuming it is the rear passenger speaker. Please refer to the list below for the wiring of your aftermarket speaker.

Radio Constant 12v+ Wire: Orange
Radio Switched 12v+ Wire: Dark Green
Radio Ground Wire: Black
Radio Illumination Wire: Gray
Stereo Dimmer Wire: Violet/White
Left Front Speaker Positive Wire (+): Tan
Left Front Speaker Negative Wire (-): Gray
Right Front Speaker Positive Wire (+): Light Green
Right Front Speaker Negative Wire (-): Dark Green
Left Rear Speaker Positive Wire (+): Brown
Left Rear Speaker Negative Wire (-): Yellow
Right Rear Speaker Positive Wire (+): Dark Blue
Right Rear Speaker Negative Wire (-): Light Blue

{: ) The audio speakers are hardwired to the audio amplifier, that's why you cannot find any fuse for these output lines. You can only do component tests on the affected speaker or speaker wires. If the fault originates at the ampli, you will need to bring it to an electronic shop.
Check also your audio settings if it is balanced.

Let me guess, you have a 2 door, right? On 2 door Blazers, it is very time consuming to get to the rear speakers, you have to remove the bottom kick plate that runs along the bottom of the door, take out the back seat, and then remove the entire plastic side wall from the interior of the truck. I took mine in, they actualy had a special price for installation of rear speakers in blazers.

bad switch or motor
To check the motor the motor has two connections. One for up and one for down. Try hot wiring the connections to check. If it works the drivers switch is bad

i have same problem with my drivers side window and now as of today,the drivers wiper wont work???????

If it does not make any noise, or sound like its getting any power, most likely its the switch.

The Window Motor is Worn out on that Side and will have to be Replaced.
