04 Buick LeSabre. Wonderful car. I had a fast flashing signal so I changed the bulb and my signals will not work at all now. I had the relay tested and replaced but still no luck, any suggestions?Turn signals arent working after bulb change?just abandon it somewhere. Take off the license plate and file or sand down anywhere where there's a VIN so the cops can't trace it to you.Turn signals arent working after bulb change?check the fuse.Turn signals arent working after bulb change?Be sure to use the correct bulbs. These bulbs usually have double contacts: for parking, turning signals and brakes. If you use a single bulb contct, it basically will create a shor circuit, thus blowing your fuse. Also, the double contact bulb only goes in one way. Have you ever seen a car ahead of you with one parking light brighter then the other, and reversing when the bakes are applied? They may have the bulb contacts reversed (like head lights, these bulbs have two separate filaments inside, one brighter then the other).Turn signals arent working after bulb change?a fast flashing signal means you have a bulb blown or bad connection inside on of the bulb sockets,
The side you found not working where you replaced the bulb---remove again, (do not have the blinkers on--leave off) inspect inside the socket for rusty sides and rusty terminals, the two little spots of brass metal in a little circle the size of the tip of a felt marker, if rusty, get a small wire brush that will fit inside and try to clean these surfaces getting them shinny to the eye, -- good---now spray inside the socket some penetrating fluid, when dry, insert the new bulb, turn on the blinkers,you should be all set, if not, you may have to attempt the rear lights also.
