Check to see if the bulb that does not flash is going bad, or is burnt out.
Hi, Is your blinker actually flashing on and off? If not it may be your hazard switch. I had to replace mine.
When you say blinker I assume you mean the trafficator/Hazard light?? If so then it is actually the Hazard switch which is located on the panel by the gear lever.
Press both blinker directions at the same time.
It is integrated into the hazard switch on the dashboard
The blinker relay is broken. It is located inside the hazard switch. Replace the switch and it will fix your problem.
Probably part of the hazard warning module - part of the hazard switch
its the hazard switch, its all one unit
blinker switch is under the cover of your steering wheel in fromt of the dash. if you are having problems with your blinker blinking , then it is the blinker and hazard mobule located in dash. this is the hazard button also . which i mean the hazard switch on dash is part of blinker module and must be replaced all together. also to let you know that's what was wromg with my 200l impala ls. it cost approx 43.00 dollars for the module at dealer as no parts shop carried them. it was a stocked item so they are probably going bad on the cars. as info: they are also quiter then the stock blinker which i like because the original was to loud. hope this helps.
Behind the hazard switch in the dash
junkyard
Maybe part of the hazard warning module
I had a problem where drive lights had burnt out,I noticed it caused the other lights to blink faster,I ignored it for a while until my signal switch burnt out,apparently the olds intrigue uses an electronic signal control that can be overheated and burnt out if you leave a bulb out,replacement hazard blinker assembly upwards of $50,else where Ive heard intrigues get shorts around the bulb assemblies,on of the few things that has not happened to my intrigue,oh cr#p spoke too soon
