Hazard warning light switch does not illuminate,but the flashers blink,is it a big job to change the bulb/switch
SOURCE: Left turn signal blinks fast in rear and regular in front
the bulb is blown out. you need to change it. also if the bulb is not blown out or if the blinker still blink fast after you change the bulb then you have a ground problem. just remove that blinker light and check the ground wire on it. if you need to replace it and find a good groun on the car. you should be fine. this is all it is .
SOURCE: turn signal flashers do not work
I have the exact same problem. I replaced both underdash relays, checked all fuses and replaced the turn signal switch. Still no turn signals. Did you figure out what was wrong with yours?
SOURCE: brake cab light works , no bed brake lights ,
Had the sam thing happen on my 95 GMC.There was a part under the dash to the reear of the parking brake were all the relays were pluged in that looked like the old buzzer box.Not sure the name of it or if yours will have the same retanguler box.Has something to do with the brake lights.The guys at my local napa new what part it was but never caught the name of it,was just happy to have brake lights again.
