Hello. Generally speaking- with turn signals, they either work or they don't work at all.

Here are the basic troubleshooting tips- if the light blinks extremely fast, that means a bulb is out on that particular side; either the left or right side. You will have to check whether the bulb is burned out in the front of the car or in the rear light assembly.

If the lights (either side) do not come on at all OR they do come on without flashing, the turn signal relay needs to be replaced.

And most likely this is the root of the turn signal working intermittently- you'll have to replace the relay- which is the easiest fix on any car.

Look in your car's owner's manual and look under the headings: electrical or turn signal lights or electrical panel, etc. It will tell you where to find the relay cluster for the signal lights. You can go to your local auto parts store to buy one (they are inexpensive) and I'm sure the counter person will show you where to find the burned out relay if not actually install it for you.

Hope this helps!

My turn signals don't always work and the flasher warning doesn't seem to work. I have replaced the multi-function turn signal switch and the problem continues. Any suggestions what is wrong?


With intermittent issues, you have to test when problem is ongoing. These issues can be a pain to track.
There is a hazard switch separate from the multifunction switch. There are separate turn signal and hazard fuses, not only check the fuses, check the fuse circuit for voltage. Use a testlight to check voltage.
Use a wiring diagram, check proper color voltage wires to and from hazard switch, to and from turn switch when problem is ongoing. I can only help you with testing.

Intermittent turn signal problem 2005 malibu


Check that the fuse for the turn signal is not loose. Sometime a firm push inside is needed. If that doesn't work replace the fuse. If it is still loose then take a narrow pice of wire and insert it in with the fuse to keep if from being loose.

The problem could also be at your turn signal stalk. Turn of the turn signal and then move the turn signal stalk in different directions and hold it. You are trying to see where the intermittent problem goes away. If it doesn't , then the stalk is fine.
