Customer Question

Well my friend jumped her car but the jumper cables were connected to the fuse box and now the radio the window switches and the dash lights are not working.
JA: How old is the battery? Have you checked the battery gauge on the dash?
Customer: Battery not bad that I know of. It was her car that was dead not my trailblazer
JA: What year is your Trailblazer?
Customer: 04
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: My friend came and looked at the fuses and said they were all good. And I wouldn't be fixing it my friend is a mechanic.

It the 04 trailblazer that's having the issues. The jumper cable got hooked up to the fuse box in the blazer instead of the battery. It started her car but after words my blazer dash lights radio and window switches were not working.

Gotcha. So let's start with the simple things, if your fuses and maxi fuses (bigger square ones) are all good, then let's try resetting the system. Take the battery leads off and rub them together for 10 seconds. Then reattach and retry everything.Let me know what happens
