I have a 1990 Honda Accord 4dr EX. I replaced the driver side window motor a few months ago because it broke. It worked fine. A week after I replaced it, I had to move the switch a few times to get it to work, eventually the switch jiggle didn't work. It doesn't work at all now. All of the other windows work fine. I bought a switch and still it won't work. I got a new motor as well and still nothing. I checked to see if I was getting any power at the window motor connector and I'm not.

Is it likely that the plug to the switch or the plug to the motor are broken? I dind't pull on the wires but I have heard that they are easily damaged.

If its not the connectors then what else could it be, the little electrical box in the door?

 

that would be the next thing i would replace. it doesnt usually go out though. check your fuses

 

I checked the fuses again. One was blown, so the window works now. I tried the old master switch and it didn't work. I must be really unlucky to get a blown fuse, a broken switch, and a broken motor all at the same time but oh well. It works now, so I won't complain.
