2005 Chevy Trailblazer 6 cyl Four Wheel Drive Automatic 70,000 miles
We jumped our car and dh put the cables on the fuse box first. Since he did that our radio, heating/air, wipers, locks, seats, etc do not work. We have tested all the fuses and they are fine. Is there anything else we can test on our own before we take it in to the shop?
