Re: directional signal only works sometime
If it is an intermittent problem, there are two likely causes. One-the multi-function switch. Two-the flasher is going bad. The first, from my experience, is the most likely, however the second is the less expensive of the two to replace. I would probably go for the multi-function switch. Make sure your brake lights are functioning normally, as your brake light wiring is connected to the multi-function switch.

if it works sometimes,then probably it's a ground problem ,check both left and right kick panels ,the main grounds are located there ,remove scuff plates and kick panels on both front next to seats.Make sure the green 8 mm bolt is tight.
The first thing you want to check for is the brake signal,without this signal it will not crank,this is the easy one make sure you get brake light,the second is to have the starter tested by a direct method,this gives the indication of the health of the starter
Everything comes through the Turn signal stalk. First, try pushing the Hazard button off and on 6 or more times. The contact points in the Hazard button derail the other contact points in the stalk. Sometimes all that is needed is to clean the contact points and it can be helped by pushing the Hazard button.
The Turn stalk is referred to as a MPS multi position switch and it is $50 to $80. The procedure to check the pin connectors on the MPS is the same as for removal. You take off the cover on the steering column, and you may have to remove the Ignition tumbler if it prevents the plastic cover from coming off. There are 2 female torx screws holding the MPS to the column. Sometimes tightening these 2 screws fixes problems. As this is a sealed case you would think it should not matter, but sometimes it works.
If you are Electrically trained, some of the MPS cases are held together by more female Torx screws. To me its Pandoras box, but you might save your money if you can successfully open and reassemble the contact points. Check your pin connectors and spray them with Electrical cleaner as well as the contact points.
I hope this gives you a direction to go and Thanks for using Fixya.
Sounds like the blinker relay. Is the emergency flasher switch on the dash above the radio ? If it is the blinkers relay is the same as the emergency relay. If the blinkers stop working pound on the emergency lights switch and if they start working then replace the emergency lights relay switch cause the blinkers is on the same relay as the emergency lights. My 2001 Grand Am does the same and I just hit the emergency lights switch and they start working again.
You more likely have a bulb that is no good. The next time your signals aren't working, pull over and check to see which bulb isn't working. Make sure the turn signal is on while checking. It should only be the left or right. Not both. Sometimes you can see the blown bulb with the hazards on depending on your model vehicle. Simply check the bulb thats not blinking for a tight fit. Then replace it if thats not the cure.
Sounds like you have a short in the turn signal switch ( in the steering column). Depending on the different functions of this switch will determine the cost. If you have one that simply works the turn signals, then your looking at about $15. I believe yours should cost around $75 since it's a multifunction type. Installation time is about 20 minutes
Try pulling out your tail light then following your wires. you should have four going into the socket one for running light, brake light, and turn, follow those down. till you find where they go and if they keep going then those are not your ground. go back to the socket and take that last wire that runs down follow it till you get to the spot that it is grounded to and some times it will be grounded in with your license plate lights. if not directly to the frame
First, let me say that the wooden boxes are a mistery. Have not got a clue.
As for the brake lights. If the lights work with the headlights on and the directional signals work, then look for the switch not working. It is usually located directly over the brake pedal, but farther up inside the dash.
Sometimes the directional signal can cause the same thing. The brake light system runs throught the directional signal system. This is how you can have on light flashing while the other is solid red, when braking with the signal on.
