#23 of 30 HAZARD LIGHTS WONT TURN OFF by candic80 Aug 13, 2009 (2:32 am)
My car hazard lights came on after taking my car into a mechanic to fix the cad converter. The mechanics couldnt figure out why they came on and it wont shut off (the switch is broke) so they took the whole plug out from under my dash and now my turning signals dont work. however, when I drove my car home and shut off car, the flashers started flashing again and now the flashers wont shut off.. and now my car wont start.There is a wierd buzzing noise that comes and goes under my column too now. Im furious and feel I shouldnt have to pay the mechanic the rest of the money i owe until this problem is resolved since I didnt have this problem before! Any suggestions as to why my car is doing this?

Replying to: ralph49 (Aug 25, 2009 8:05 pm) Ralph, Stopped it by a good friends shop, just to verify; if it's the body control module (bcm) a new one can only be programmed by the dealer. Went by the dealer also, they said that it also could be in the ignition switch, the service rep said it could be the bcm as well but pushed more for the Ign Sw. My gut feeling and past experience if it was the switch when keyed to start and blower/cruise does not run/work they would continue to not run/work until the next time that the key was turned. My problems will stop and start intermittley while driving. It also does not run/work when first started. Also I have the info center for mileage and traveling direction (N, E, W & S) it also does other functions. I have noticed most times that the blower/cruise is not working it also goes out, but there has been times that it does continue to work. Are you seeing this also? Don’t know if you have this option on your car. They would have to pull the codes for a cost of $89+. Don't know about you but I'm old school and like my 67 Chevy PU. I have been turning wenches along time and can fix anything on the truck. New is great as long as it is working but when it's not working on these new rides it can be costly. Please let me know if your fix works. My problems have also been acting up for almost a year now. Just a side note; always liked the name Ralph see I’m bias being my father carries this name.
