I have a 2001 Honda Civic Ex-140.000 miles on it and runs great up until this Month. In the month of May, I had a tune-up, stratus bar replace under car, brakes, and rotary, tires rotated and front end alignment. Went on vacation and put on 1200 miles on it. In the month of August my brake light came on, the same time my lock mechanism stopped locking all doors but all doors can be locked from the outside using the key. The air conditioner stopped blowing cold air inside. The seat belt indicator stopped working and no light comes on when the seat belt is removed. the windshield wipers have three gears, and the first gear stopped working, So I took it to the dealership and they said I needed a new coil and air compressor which was working after the battery was unconnected but when the engine shut down then everything stopped working again. I do believe that all these items that are malfunctioning are relative in one form or another. That is the brake light is on constantly on, seat belt icon does not show on dashboard, air condition not blowing any cold air.
