03 truck turn signals wont work
when i first bought my truck the turn signals worked intermitantly. Almost always in the morning they wouldnt work then id get off work and they would work all the sudden.
I had called the previous owner to see if there was something i needed to know about it and he said just to blow some dust cleaner in the fuse box. Never helped the problem. Anyone have any ideas what could be keeping my turn signals from working. They dont work at all now. |
Re: 03 truck turn signals wont work
shot in the dark, do your hazzard lights work? if not replace the flasher unit, not sure where they are in your truck though

Re: 03 truck turn signals wont work
changed the hazard flasher relay, still no turn signals. anyone else have any ideas?

Re: 03 truck turn signals wont work
maybe bad ground wire?
if it is still under warranty take it to dealer and have them fix it |
Re: 03 truck turn signals wont work
Probably the turn signal switch/multifunction switch. have you checked all the fuses?

Re: 03 truck turn signals wont work
I wouldnt even know where to start looking for bad ground wires

Had to change the multifunction switch on my niece’s 1999 Olds Aurora last weekend for the same intermittent turn signal issue. Easy to change but be sure you remove all of the airbag fuses before removing the actual bag. |
Re: 03 truck turn signals wont work
Good idea, how do you go about removing the air bag?

Did you replace the hazard flasher unit? Or just the relay? My brother's 01 had this problem, where signals would not work, and if he pushed the hazard button the lights would light up solid with no flash. Replaced that unit and it fixed the problem. |
Re: 03 truck turn signals wont work
so i guess im dumb but what do i need to do after i get the air bag out? take off the steering wheel?
what part am i looking for? anyone have any pics or diagrams? thanks |
