Hi there. It sounds like you may have blown radio fuse. After some research, I found that the radio fuse is most likely in the right side instrument panel fuse block. Locate and inspect the fuse with a digital volt/ohm meter. If you do not find supply voltage on both sides, then the fuse is likely blown; probably due to an unseen/noticed short during a repair. Replace the fuse and recheck for supply voltage on both sides of the fuse and at the radio connector. If the connector does not have voltage, then there is either an open circuit/broken wire or it may be installed incorrectly. If voltage is available, reseat the connector in the radio to make sure the connector is all the way in and providing a good connection; slightly tug at the wires to check for loose terminals and correct as necessary. I strongly suggest having a qualified technician perform an inspection to avoid any additional concerns from occurring or replacing unnecessary parts. Your Mechanic has several available technicians that can assist you with a radio does not work inspection.
