I know the part is online for ninety bux but i dont know if i can pull this off myself from a utube vid i watched?? Any advice?? Its an 03g35 coupe and im in the Orlando area THX!!

I was in your situation a very long time ago and had to get rid of a 21 year old car.

I only buy new vehicles now that come with all new parts and a warranty.

You can obtain a cheap multimeter for testing at Harbor Freight

Don't automatically assume the motor is defective without proving and testing.
Could be a fuse, a poor connection, or a missing ground or even the motor but you need to either do the troubleshooting yourself or pay a professional to do it.
Knowing and becoming friendly with an Infiniti Service Manager and their top fully trained technician that does electrical troubleshooting is a big plus. Make some homemade chocolate chip cookies for them if you think that might help you get some troubleshooting assistance.

See page GW 19

Good luck
