Yesterday i was getting ready to leave my house and just as i was about to brush my teeth my horn starts going off like crazy and i try to start the car and the ignition wont turn over so i have to use the backup key to start it but the horn is still going off so i go under the hood and disconnect the battery "it finally stops" so i go inside the car to see if anything is wrong ,and i see smoke coming from the dash "at this point i am tripping out" i look at my gauge cluster and the needles are maxed out no power to it but it seemed as if there was a sudden short circuit to the cluster, so i hook the battery back up and the horn starts going off again so i disconnect the horn relay and it stops and i go to start the car "it starts" but the cluster is inoperative same with my signals and window switch so its down @ mazda right now getting check out but i was wondering if this has happened to anyone before???
