replace

My driver's side window won't move at all.. it won't even make a sound. I got a new motor but I'm not totally sure how to install it.. any suggestions?

New member. Any help would be appreciated. How do I identify which alternator is on my 2003 5.3. I am being told there is a 105 and 145 amp model that were put on these engines. Is there an easy way to distinguish between the two? :eek:
