Okay, replaced the window relay behind instrument cluster and got the front passenger to roll up... Fuse "b" blows now though killing frnt drvr/rear pssngr windows. The previous owner has something aftermarket wired from +battery to fuse "b" (pic 1). I opened the fuse and it was blown so I replaced it with a new one. I brought the blown one in to make sure I got the same one (20amp). I put in a new one and it blew immediately, another one and the same result (pic 2)... I'm not versed in electrical at all but a short must be to blame, right?

Also, when I cleaned the switches I must have sabotaged the "child lock" and lost a part or broke something because it won't stay depressed. It looks like something on inner part of lock switch should catch the outer part to stay depressed (pic 3 & 4)... Does anyone know if that is the case? If the lock switch grounds all the windows then is this where my issue really lies?

I tried the 12v to socket 2 and ground to socket 1 to roll up windows but no love. I did disconnect the battery before doing all this and had it disconnected when I attempted the trick, does that matter?

I have tried really hard to figure this all out via book and online to keep from bothering you all with my problems but I just don't know what to do now... Any help would be appreciated more than you probably realize. Thanksabunch!
