I purchased a used 2006 mazda 6 today. For the age it’s in decent shape and lower miles. I bought it as is but got the dealer to knock off $300. Im having several things not working. The radio doesn’t turn on not does the digital display above the radio. None of the interior ceiling lights turn on. I’ve heard this might be a fuse and they are connected? We’re not getting any illumination on the panel below the radio either. As in for the controls for the heat and what not. Im debating taking this into a shop but I need advice. I know the battery was supposedly recently replaced.

I also noticed tonight and im stupid for not checking this earlier. The rear parking lights aren’t illuminating when I have my headlights on. The backup and turn signals work and so do the brake lights. Could this be fuses or maybe just a lot of bad bulbs?

 

Check all your fuses, both under the bonnet/hood & under the dash.

 

I went to auto zone and bought a fuse tester and kit of an assortment of fuses. I basically made sure all the fuses were the proper amps and that they worked. I replaced most of them anyway. Unfortunately this has not solved the problems. I can only think maybe one of the relays are bad? Maybe most of the light bulbs are burned out? Just seems as it’s connected somehow. Maybe a wiring issue? AutoZone said the battery could be bad to. Maybe I should suck it up and go the Mazda dealership tomorrow. I also noticed the odometer gets reset every time I turn off the vehicle.
