The windows on a Chevy Blazer may not roll down if the power window mechanism has been damaged or broken. This can be repaired through a reputable mechanic.
Because it hates you!
There is no safety lock on the rear windows. They roll down that far for reason. The wheel well is in the way.
The Mazda van (MPV?) and the Toyota Sienna have side windows that roll down half way.
The rear window frame is shortened because of the wheel well, to get a full roll down I believe only the suburbans have that capability.I have a 95 Tahoe has the same half roll situation.
broken switch or fuze
I do not believe there is a way.
Roll Windows down, roll back up and leave switch pressed for 5 more seconds, same for the sunroof
Check the switches....
LINKAGE OUT OF ADJUSTMENT OR POSSIBLY THE PAWL IS BROKWEN OFF THAT ENGAGES THE GEAR.
replace the window motor.
A fuse.
Sounds like an electrical short. Take it to someone certified to do the repairwork like a Pepboys or your dealership, but the dealership will probably charge you more.
