I have a 2007 equinox and the drivers side front speakers stopped working.

check for sound balance on your radio maybe you or someone have mute that particular speaker if well balanced, then you have a dead speaker or broken wires.

Beings as everything that stopped working is on the passenger side, I'd think some wiring got disconnected or broken.

Its the wires in your drivers side door jam, the become brittle from constant opening and closing of the door. I had the same problem with my 1996 Camry but it was effecting my power windows and door locks also, What I did was take the rubber tube out of the drivers door with all the wires running into the car, cuting them all off, resplicing all the wires and connecting them with connectors, wrapping each one with electrical tape and then all of them together with the tape and after I did this all my windows works, all the door locks and the front speaker too! I did this over a year ago and havent had one bit a trouble since, good luck!

You'll need to replace the solenoid (motor) that doesn't work. Not hard once you get the door panel off. I suggest you buy the correct part, not a universal one.

check fuse .if fuse good you got a bad ground.

when mine stopped working,the right speaker, i removed the door panels then swapped the speakers. and still the right speaker didnt work. so i got a radio from a junkyard and installed it. and now all speakers work fine.

Check inside wiring by the driver's side door hinge. Remove the rubber boot and you will find broken wires. Make a splice and you are fixed!
