1991 blazer 4x4 4dr."locks,oil presure,volts,ABS problems.

[sti4race]

I have just got my self a 91 blazer 4dr. 4x4 and so far I'm having trouble with the windows "front don't go down/back go down very slowly, the locks will only lock from the driver door and it somtimes has a gletch when I shut the door, The ABS light stays on all the time, The right rear brake skreches, My oil presure stays at 80 when driving and the temp gage flashes when I take the HWY across town... so any input would be most helpful.....

The ABS light comes on when an error code has been recorded and stored. If your right rear brake is squeaking, it's probably giving an error that the ABS computer is picking up. Have that brake checked out to make sure nothing is afoul with it--poor braking ability is not cool.

Should run up to 60-80 cold when started, then drop down to 25 posi while hot at idle, then 40-60 at load while hot.

For the Windows you need to check the fuses and what not but in my 1991 all it needed was a new motor in the passenger window and im back at 2/55+

fuses are fine and the motors look ok but I was thinking it could be a short in the switch harnes becuase its only the front windows that don't work...

how can a motor look fine did you test them? each door has its own motor

[sti4race]

I know each door has a motor.... they look ok because there is no burn marks or gruves in the armetures or around the wires. I think the motors in the back doors may need to be cleaned and oiled or maybee replaced but since I need a new test light I can't tell if the front motors are getting any power, But today when I closed the door the locks shuke and studerd like somone was repedly pushing the buttons.
