Hello & Welcome,

 

Do you have a test light or multimeter to do some testing?

 

Thanks

Customer: replied 8 years ago.
no
Expert:  MCVGreg replied 8 years ago.

OK - Thanks.

 

Is there any way you can get one of these tools, such as borrowing from a friend?

 

 

Customer: replied 8 years ago.
yeah but is that the only thing that it could be (a fuse)
Expert:  MCVGreg replied 8 years ago.

It could be a fuse. Sometimes there are fusible links that are in there too, for some of the main power drawing areas. That is why I would like to do some testing.

 

Did you actually see any sparks or indication of problems while changing the window motor?

 

Do ANY electrical systems work in the car?

 

Thanks

Customer: replied 8 years ago.
no i didn't see any sparks while changing the window motor. none of the electrical systems are working
Expert:  MCVGreg replied 8 years ago.
Did you disconnect the battery before starting the work?
Customer: replied 8 years ago.

no

Expert:  MCVGreg replied 8 years ago.

OK.

 

I think the first step would be to get a 12 volt test light or multimeter to be able the check the connections and fuses as close to the battery as possible.

 

Please let me know when you have one of those and then we can proceed to do some tests.

 

Thanks, XXXXX
