Nikon L35AF2 doesn't stop shutting and winding the film

I opened up my Nikon L35AF2 to exchange a broken glass in front of the viewfinder. When I put it all together and put the batteries back in and hit the shutter button once without any film in, the camera suddenly started exposing and winding the film forwards. It doesn't stop whatever I do, with film in or without, with the back closed or open. Of course when I remove the batteries it stops, but when I put them back in it starts again. While it is doing all of this, I can't push the shutter button, no matter if the camera is turned on or off. I can open up the camera again of course, but I don't really now where to look for the problem. Please help :/

You likely shorted something or stuck the shutter button in the down position.
The camera uses inrared sensors to sence film, time between two sensors, and similar functions. If blocked motors will not run or if not blocked a motor will run contineously.
Open the camera as before and inspect it.
