2002 mdx 117k, ac blower not working on front or rear..we checked all fuses and relays, opened the resistor and looked at fuse, looked good, but when i jump it with a wire to both ends, without providing any juice, the blower works, does that mean the resistor is bad?

 

Yes

There are 2 of them.

1 for front blower

1 for rear blower
