Yes, the grounding wires for the turn indicators get easily corroded - clean them.

    Intermittent connections on the bottom of the fuse box under the hood. Also causing intermittent horn and windshield wipers.

    That is not good, so many bad connection at the fuse box. Take every connector from there and check it - crimp it a little bit more if necessary. If the problem is in the fuse box then you must replace it immediately - otherwise you may end up with a fried ECM. And this is way more expensive to replace.

I have 2001 buick lesabre limited. The left turn signal light stays on constantly on my dash and flashes fast when signaling. I replaced all 4 turn signal lamps in front and still stays lit and fast.


Did you check and see if they were working? If side lights are part of the turn signal, blown bulbs there will cause this also. If one doesn't work, look at the plug. bend and clean the tabs inside it to contact the bulb. If a broken wire, they usually break at the plug. Check for power and ground at the plug.

Jeep 2005 left turn signal not working. all bulbs good


all bulbs good by what method>?
guessing?
bulbs can be good, bad or shorted,
testing them takes skills,
the flicker usually means that side is shorted.
remove all left bulbs, now put in just 1 new bulb. (not used)
work now. repeat, with other socket a new bulb.
Im not teaching how to test lamps ,ever, for 50 cent part.
can but wont.
if the blinker (turns) still fails. then find the short in the wiring
I always start at left rear.
looking for UHAUL trailer hacks there
then left front for collision damage not cured correctly.
see?
if still bad, then the whole left side wiring must be inspected
starting at sockets.
this is on all cars, made, but not 2008 up, on jeeps
on those you scan it first.

I have a Chevrolet cobalt and the left turn signal will not work the inside light on dash flashes fast. I have changed the light bulb still doesn't work.


Fast flashing usually indicates that one of the exterior bulbs isn't functioning. You've checked front and rear signal lights, right? If the bulb is good, it could be corrosion in the socket, bad ground, broken wire, etc.

2003 Jeep liberty right front turn signal


why skip RR lamp? what does IT DO? be like 1st 1st look.
dim, out, fast?

the rapid is talking to you
it means current is wrong,
shorted, or open lines. to the right.
its the wiring
if the bulbs are like 1157 brass base bulbs
why not replace them first , they can short inside,
asking online for guessing is silly, why listen to 10 examples for this.
but is cut wires.
shorted wires.
keep i mind the blinker asks funny for both opens and shorts
its a feature, that.
low current or too much.

the acid test is connect 2 TEST bulbs in parallel to the multi-function switch output right side,
blinks ok now, bingo bad lamps or bad wiring, from there to the right side.

if the hazard fails you never said????
if rigth front is dim or dead the bulb is blown or shorted
if new bulb there , then the wires are shorted.
to it.
the only help on line worth squat is how to test and use your meter.
you can, check for voltage
you can check continuity on that line (its just 1 wire)
and check for shorts on that wire to ground (lamps pulled right side to do that, lamps read 0 ohms cold)
look for collision damage RF? behind lamp sockets?
be first.
in my book.
looking is always first. sure.


I have your SM book open now, chapter 8w-50
the haz/blink module has just 2 pins, left and right out.
pin 3 on the module runs front and rear blinks, (a fact to know)
RF is BR/RD, brown -red stripe?
all comments USA on USA forum. USA car.
ok?

the right side lamp (sidemaker) only blinks turns if parks ARE oFF

Id try 2 new blinker lamps front and 1 rear.
that be first. or test the lamp on a battery , and no not get burned fingers hot wring a shorted lamp.

wish i knew
what rear did
and what both did on HAZ
out, dim or to fast.

My left turn signals don't work.you can hear the clicker working normal and the courning lite come on. If you leave the signal switch on the turn lite will flash once in a while and also the lite on...


You most likely have a bad bulb, if the front bulb goes the rear wont work and vise versa both bulbs must be good to complete the cirrcut. Even though you have no lights you should still hear the flasher relay. Bulbs are cheap just replace both and you'll be good to go. Good luck

2000 taurus left turn signal flashes rapidly and the left rear turn signal lamp does not work. Does ford have burned out bulb sense circuit that would give this indication? The right side flashes normally.


Yes - the fast flashing is a warning that a bulb is burned out. Change the bulb (be careful to put it in the same as the old one as it probably is 2 bulbs in one , parking and turn/stop) and you should be fine.

I tried replacing the right rear turn signal twice. Still only get a fast on-off flash on the dash and only the right front signal works. Left turn signals are fine.


The circuit boards in Chevrolet tail lamps ar notorious for going bad. Dorman makes a replacement circuit board, part number 70006 . the same part number will fit either the left or right side of your Trailblazer.
