These 2005 Chevy Malibu Complaints are extremely common in this make and model vehicle. According to Car Complaints, this was a design flaw in the vehicle that caused the bulbs to burn so hot that they burned out the lights and melted the turn signal covers. The gaps introduced by the warped light covers have led to electrical system horror stories about ...

Yes you can often repair turn signal flashers! A variety of things can be wrong: here's one of them. Solder joints on the relay printed circuit boards are especially vulnerable to stress cracks, due to the clicking motion day in and day out. Take the case off the relay and use a jeweler's loupe to inspect for hairline cracks, especially cracks those that ...

I don't know that car specifically, but it sounds like the auto-cancel mechanism is bent or mis-installed. Since it is integral with the steering column, you will probably need to pull off your steering wheel and get into where the switch mates with the column. There will be a plate or ring on the column with a tab or the like that will move a lever in the ...

I can think of several reasons straight away: Cheap Easy to replace Have a very distinctive click that makes it obvious when they are on, and when a bulb has failed Are very well understood Anyone can fit one without needing to understand much about electronics

On the Expedition the hazard, lower brake lights, and turn signals all route through the multi-function switch. Gain access to the multi-function switch connector and back probe the light green wire while pressing the brakes. Does it have power? If it yes back probe the light green/orange and orange/light blue wires while pressing the brakes. Does it have ...

This is symptomatic of a loose or poor earth on the lamps. It may be either the front or the rear earthing point. The other item to consider is the indicator/hazard unit, it may be starting to fail.

Some cars have a separate flasher relay for the Hazards - if that's the case then you might have a failure of the primary flasher relay? The signal initially not turning off suggests a possible failure of the switch though - It might be worth disconnecting the switch (there's usually a connection somewhere under the column) and testing it separately? I'm ...

The front light bulb has failed. Simple fix!

I'd check the ground strap/contact to ground from the blinker to the chassis first. Chances are there's a problem with it an it "grounds" via another bulb when you also apply the brake. Using a multimeter, check the resistance from the ground on the bulb holder against the chassis first, then check blinker ground against both contacts for the brake light. ...

The main purpose for this is so other drivers can see your turn signal. The LED lights are so intense, they do not allow the oncoming driver to be able to see the turn signal. By turning the LEDs off, it becomes readily apparent.

Usually the breakage is some small plastic part that you're not going to be able to reasonably repair. Typically a whole replacement unit can be had pretty cheap from a junkyard anyways. Normally not worth a repair effort.

This sounds most likely to be a fault in the switch in the indicator stalk - normally you have a physical linkage which keeps the turn indicator flashing while you turn a corner, then it releases as the steering wheel straightens. I can imagine a couple of ways this could fail and allow the spring in that mechanical return to perhaps trigger the right ...

You probably need to change the flasher unit to match the load of the LEDs. If you can't find a custom part specially made for this, I suspect you can do it by replacing a capacitor inside the unit. This should fix the flashing rate, but I'm not sure whether or not it would fix the indicator. Honestly, since this is just a turn signal, you might just be ...

Two things. First, you can almost guarantee with the blinker going fast one of the bulbs are out. This might include any of the small bulbs which are side markers as well as the main lights which are front/rear. Look around the "good" side of the vehicle with the blinkers on to figure out where the small bulb might be, then look to see if it is flashing on ...

The last time (many years ago) I changed out a turn signal switch it was a PITA because of all the anti-theft devices wrapped around the steering column. By the time I got to the switch I was cursing up a streak and I never did get the thing back together right. Never again. With airbag systems on the steering wheel it can only have gotten worse. My advice ...

A multimeter is going to be your best bet as, depending on exactly what the cause is, you may have one of the following: a partial short circuit a partial open circuit a faulty relay You will need to follow the wires to find the physical problem. The good news is that it is likely to be near the back, as closing the trunk must have jarred something ...

The way most indicators are set up is that the load on them affects the flash rate (those older models used current flowing through a bi-metallic strip: the bulb current heated the strip which then broke the flow of current). Modern indicator circuits are often much more electronic, but the same setup is used to make it obvious to the driver what the ...

There are two filaments inside a turn signal bulb. One of them is dim for the park lights, the other is bright for the turn signal. The bright filament can break on one end and land on the dim filament. Anytime the parking lights are on it makes both filaments light. The turn signal can still function depending on where the break in the filament is. This ...

Check your earth/grounding points for the lights. Lights illuminating when they're not supposed to is a classic symptom of a bad earth.

This sounds (to me) like a grounding / electrical connection problem. I'd check the connections on all parts of the system: The relay that was replaced, and its socket / connectors. The signal switch itself. The connections to the indicator bulbs themselves. The wiring harness connecting everything. Since it sounds like it's on both indicators (left and ...

Almost certainly a poor connection within the bulb holder. You might be able to clean up the connections within the holder with a fine bit of sandpaper or "wet and dry", then adjust them with a tiny screwdriver to improve the contact, but it's probably easier to get a new unit...

I have a somewhat similar problem. I will have intermittent clicks when not using the turn signal in my 2006 VW Golf. It is caused by tiny metal shavings that are suspended in the grease that is used in the turn signal and it will occasionally conduct just enough electricity to trigger the turn clicker without actually sending enough electricity to turn ...

Forgot about this question. Anyway, replacing the bulb fixed the issue, though unlike as Larry suggested, both filaments were intact. Also unlike as Drake suggests, the bulb was of the correct model. Still no idea what the cause was, but it's fixed now anyway.

I have also seen it from putting the wrong bulb in the socket - often done by another shop or parts store even. Of you've had one replaced, pull out the bulb and look at the bottom. Make sure there are the same number of 'nipples' on the bottom of the bulb as there are in the bottom of the socket. When i worked as a mechanic, it was a very common problem i ...

It seems your multifunction switch is probably bad. It should be fairly easy to pull this switch to inspect it. I found these instructions to gain access: The turn signal canceling is part of the function of the 'multifunction switch'. This is a switch mounted on the steering column by 2 screws. Once you take the covers off, you can see the ...

Check what happens when the hazard light is switched on. If hazard works correctly then the problem could be with the combination switch(light). It is better to get it replaced at the workshop is my suggestion

How 11-pin flasher relays work internally. See this wiring diagram: It is for the BOSCH 0 335 210 250 flasher relay (same as yours, only for 12V). The diagram shows the internal components of the device logically (physically speaking, there are some more inside). How to connect 11-pin flasher relays. According to the above diagram, this is how you ...

You can try to look for a battery drain as shown in this video by Scotty Kilmer. If you find any drain in the battery you can fix it and this may solve to whole problem. EDIT: In the video Scotty uses a test light (that you can buy in AutoZone for about $10) or a 1 Ohm resistor rated at 10 Watts and a voltmeter (In case you have one lying around, otherwise ...

From what I see, the bulb is a 1157A. These are very standard bulbs and can be picked up most anywhere (Walmart, AutoZone, Checkers, O'Reilly's, etc). The "A" in the identification indicates it as an amber bulb. You can find the 1157 which is the same exact bulb without the amber tint.

Your blinker module is broken. This is on the left side behind the steering wheel. There is some mechanical part connected to the steering wheel. If you turn blinker right, some little tooth came out of this module. Then if you turn the wheel back, it touch the tooth of the steering wheel and release to blinker to neutral. Maybe if you build up this module, ...
