95 240sx power windows not working.
 

having an issue with my windows not rolling up or down. checked all the fuses which are all good and decided to try changing the relay but when i did still same problem.
could it be because my alternator is not working?
both driver side and passenger dont work. did a engine swap awhile back and windows worked fine before and after swap it stopped working.

check your window amp?

I didn't know the window amp would effect both Windows. Hmm news to me

Did you check the 25A fusable link under the hood?
Recheck your grounds too.
