I have a 1993 chevy s10 pick up 4x4 drove it around yesterday and everything worked fine parked it outside my brothers house for a few hours drove it home got home and when i went to roll both power windows up they do nothing and i tried the door locks again nothing on both doors..... I have replaced the circuit breakers on the fuse panel and tested the switches on both doors and get power on both sides all the way up to the power winow motors same with the power lock motors but still wont work.....is there a relay somewhere that im overlooking or something im missing? my next test is to hook power directly to both motors to test if the motors still work but all this went out at the sametime and first time it has been a problem
both power windows and power locks stopped working on both front doors sametime on 1993 Chevrolet S10

Power from the master switch goes to both door. The accordion tube that goes between the door and the door jam (filled with wires) probably has a broken wire(s) This is really common on GM products

If they both failed at the same time it is more than likly a fuse which would be located above the drives pedals. It will say either accessories or power window.
