Window motor or regulator

Hi guys,

Passenger's window is not coming up, it's been down for at least 2 months.

How do I find out if it is the window regulator or the window motor that needs replacing?

What are their part numbers?

 

Also, my ground battery terminal doesn't tight enough for my liking, the car still turns on fine but I would like to replace it, any ground terminal recommended?

When you have the door panel off you can also check if it's the motor or switch by hooking two wires up to a spare battery,if you have one and wire the other end to the motor. If it the operates up and down its your switch that's faulty.

Coming back to this, thanks, the regulator is working with a spare battery. I bought a switch from Keiron and still doesn't work. Any chance of the issue being instead with the drivers side switch for the passenger window or a fuse? Everything else is working on the car
