1996 chev pickup - left rear turn signal does not work. Front turn signal is blinking fast. Have replaced bulbs and the lamp bases in taillight section. Right side is working fine. Could it be the flasher?

Check the fuses. If not the fuses it could be anywhere from turn signal switch or wiring issue from possible pests getting into vehicle.

Make sure that all the bulbs are the correct ones and have a good ground.

you must fit a matching set of bulbs front and rear check the bulb contacts may need cleaned.

Sounds like a bad connection somewhere.

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.

I just had that problem with my jeep cherokee and either your bulb has burned out or it is burning out. Time to replace it. Turn the signal light lever on the side that's flashing fast, get out of the vehicle and look at the front and back signal lights and replace the one that isn't blinking...hope this helps.

the fuse is broke

check all fuse for the taillights again, make sure all bulbs are good. it blink fast because a bulb is out.

any increase in bink speed is direcly related to a bulb being burt out.

Replace the bulb that stays on and doesn't blink, if that doesn't solve the problem, let me know.
