Ps2 controller lights up on analog but doe...

i have 2 controllers with separate issues. they are both the cheap game stop controllers. one issue is that i plug in my controller and nothing happens, wont respond at all, when i press the analog power button on the controller it lights up but that is all i can get out of the controller. the other controller works but the X button and up and left seem to be stuck. when i goto play a racing game the car is on full throttle and it goes hard left without touching the controller. i know i could just go out and buy some new controllers but I am real short on money and the wife told me no lol is there any way that i could fix this?
