My ac was not working and I took the dealership and they told me the fuse box needs to change, so I got a fuse box and took the negative battery cable out and replaced the fuse box but my car doesn't start now. 2007 Buick lacrosse.
Should I jump start? the car has the battery, I have lights etc but it doesn't start. I don't know what happened.
Edit: I put back the old fuse box and still doesn’t start. It cranks but doesn’t start. Maybe I placed some relays in the wrong spot?
