I have an electrical issue that is beyond me. How do I fix faulty turn signal?
I agree that there is a short.
what could have caused the short?
Has the truck been in an accident?
did you remove the dashboard?
or any other 'under the dash or in the steering column' work?
IMHO, i don't think the cat conv had anything to do with it; the cat is on exhaust mid-vehicle and wiring for items mentioned are in steering column and dashboard where light switch is located.
Unless the mechanics that did the cat work somehow damaged the steering column / ignition switch that may have caused a short... but that is a stretch.
I have not had to deconstruct my steering column or have to deal with the turn signal, so not sure if you have to pull the wheel off first to get at them or not. But if you do, study up on removal process or else you can 'activate' the air bag.
Since I do all my own repairs, this is how I'd go about figuring it out.
Call 5-star dealers until I find someone willing to have a conversation about my problem... find the know it all guy that has answers for everything that 'enjoys a challenge' like this. Don't limit your calls to local dealers... I have found guys that help me that are 3 states away!!!
Let him know that your a DIYer and need info. A lot of times they are willing if they have time. Don't call on Sat at 8 am during weekend service rush.
Ask lots of questions.
Have you ever seen this problem before? What do you think may cause this? Does this sound like a wiring short?
And you most likely will hear 'well i can't diagnose over the phone...'
So I always let them off the hook with 'I agree and not gonna hold you to anything said here, I'm just needing an expert opinion to brainstorm with'. works every time. Continue with questions.
Do i have to take wheel off to get to signal mechanism and or ignition switch?
Ask for stuff !!!!
Do you have diagrams available that I can get/download? Is there a website for exploded diagrams or wiring diagrams?
where can I get copies from a tech manual?
Once you get a lead, try his/her suggestions.
Since this is electrical will mean trying to find the short so you need the equipment and know-how to do that. Use internet if you don't know how to find a short..... Many youtube vids on this and other topics.
before you start taking things apart, do the easy stuff first.
Is the ignition switch damaged? do you have a 'key cluster' of weight that hangs on ignition?? had difficulty turning ignition or inserting/removing key form ignition? Do you start/stop via key hundreds of times a day? could the ignition switch be worn out !?!?!?
are you good at reading wiring diagrams?
Follow the wires that are causing the problems...
signal, headlights and ignition switch.
Look for the obvious first. Broken, pinched, partially cut wires, exposed wires contacting ground....
I wouldn't think that fuses could cause this problem,but check to see if all are ok.
Then I would try eliminating all problems by removing the fuse for the headlight and turn signals.
with fuses removed, start/stop with key switch with light on/off.
if successful, put in signal fuse.
if successful, or not, try left signal.
remove signal fuse, put in headlight fuse.
start/stop with light on and off.
Does it continue to run until lights turned off?
use the left signal even if signal fuse is removed...
Try all different combos here, it may give a clue to the culprit.
Hmmmmm. Looking back, I think i would try to do as much investigation as possible (fuse check, wiring check and the 'fuse tests') prior to calling svc mgrs... it will give you some knowledge of what your dealing with so you can have an 'intelligent' conversation.
hope this may help somehow. Just kinda ramblin I know, but I can't diagnose it over the pho... internet. ;^)
On the other hand, you have the 'no fix' option.
You could just continue on with an 'interesting vehicle'.
Just make sure there are no police cars around when you don't use the left blinker. Or just take 3 rights.
And look on the bright side... with the weird light switch, you'd never have to worry about leaving your lights on!!!
