Any help would be appreciated.
1988 Silverado C1500 5.7
Power windows were not working so I installed a new switch on driver side the window would work most of the time but sometime when you first started off it wouldn’t work but would start working after driving a short distance. I figured there might be a bad spot in the motor so I installed a new window regulator motor assembly and it didn’t work. I tested for power at the switch and at the connection at the motor have power on both the up and down contact but when I connect it to the window motor it doesn’t work and it trips the fuse
/circuit breaker so I then have no current when testing with the test light but if I wait a few minutes the fuse resets and the test light will light again at all the test points. I’ve looked at all the wiring that you can see where it runs from the door to the body and see no problem at all with any frayed wiring.
