I have had several weird things happen with my car today. First, the alarm was chirping whenever I opened or closed a door. Then, the gear shift froze up and I had to mess around with the shift lock to get it out of park (this is still happening). Then, my turn signals stopped working. Any ideas what might cause this cluster of problems? I replaced my headlights a few days ago and am wondering if I somehow caused a short in the electrical system. Any suggestions would be much appreciated!
