newbie with rear window problems

[grater]

Hows it going everyone- I just recently purchased a 95 4runner and iv been having problems with the rear window,and windshield wiper....to put it short and simple nothing works at all back there now...here are the symptoms

when it first started giving me trouble the rear window would go down by itself,i managed to get it up half way with the switch up front and it dropped on its own again.I checked under the panels of the tailgate to see if any wiring was disconnected,while doing so i saw that the motor was running on its own with the ignition off and key out!?
a couple days later after manually lifting the window up the rear wiper went crazy and turned on by itself and wouldnt turn off,so i had to pull the fuse.
ive checked fuses
ive replaced the motor and relay
and ive made sure the wiper was seated properly
after alot of research i havent really found any possible answers
So does anyone know of anything else it could possibly be?
grounded wire somewhere?
Thanks in advance

I would check the front switch and the rear key switch for proper operation. It's possible the rear switch is no longer moving with the key and was stuck on. Also check the wiring/connectors to the wiper and the rear switch.

i forgot to mention that i did replace the switch up front,as far as the rear key switch,ill check that tomorrow,that would make sense though,because the key doesnt even work to unlock the tailgate
thanks for the suggestion
