window problem and heater prob.

hey guys my driver side window doesn’t go up to great, its a power window and when it gets near the top it starts to wobble a lil bit like it loose, how can i fix this?? when i had my g1 that happened, then the window went out of line and was fucked up, think it was my regulator, can anyone confirm??

also i just noticed that when i turn my fan on a higher setting for the heat to come out, it doesn’t come out any faster, does that mean my fan is dead or maybe the knob is bad?? i don’t want to have to take my dash out for this, but i’m sure i’ll have too ,plz help
