Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hello,I will be glad to try and assist you with this,Welcome to Just Answer.
Did you check all fuses under hood and in interior for one that could be blown?
Sometimes the fuse wont be marked cigar/lighter/aux,etc. it may have a different name to it as it may power up another component as well.I believe the fuse for this should be under the hood but it could also be in the interior fuse panel,I would check all the fuses in the vehicle inside and outside and most likely you will find one of them blown,it could be marked inst.lps,outlet,power source,etc.A blown fuse is the most common failure for this concern and usually blows when something is plugged in that shorts the positive and negative together.
