I have a 2002 4x4 4-door blazer. Recently, all four power windows stopped working at the same time. It's obviously not all four motors that have gone bad at the same time so could someone please help me with the electrical problems! The wiring diagram in my Haynes manual is useless as it does not describe the wiring in my Blazer. For starters, there is no yellow hot wire.

I have checked all of the fuses (since there is not one labelled as power windows) and they all are ok. I have also replaced the power window/power lock switch in the driver's door. This did not help. I checked the wiring between the door and the body and it is not cut or pinched an any way.

I have read in places that there may be a 30 amp breaker somewhere under the dash or under the hood. Could someone help me find this or something else that may be the problem? Summers here are hot and I would love to be able to roll the windows down!

Thanks!

 

Hi,

I have the same blazer power window symptom. I see no replies to this. Did you ever solve your problem? How?

I smelled burning, then my 4 power windows were inoperable. I replaced the driver door switch pod with a new one. The windows worked briefly. Then putting up the rear driver side window went very slowly. It made it to the top, but then I smelled burning again and now all are dead again.

Thanks for any info.
