My 92 Rodeo's right turn signal does not work. The left signal works fine, the hazards work fine and these use the same bulbs as the turn signals, and when I attempt to put on my right blinker the normal clicking sound is accelerated to an almost constant buzz. I am about as clueless as they come... I thought for a bit that it might be the flasher unit but I don't know if the left flasher would work if this was the case. Faulty wiring maybe? Any ideas/help would be greatly appreciated, Thanks!

Maybe it has a dual filament bulb and the turn signal uses one and the hazards use the other?? Usually when you get the accelerated clicking sound it means you have a blown bulb or its on its way out. Have you checked the bulb?

hmm thanks... but not only did I check both bulbs, I replaced both of them as well earlier today. Same problem: Hazards work, left signal works, right signal broken.

Your Turns signal switch is malfunctioning.

I just had the same thing happen on my 91 rodeo.

The culprit component is the turn signal switch located in the steering column.

The part is expensive. I located a good used one through an autowrecker and bought a steering wheel puller kit.

The whole job should take about an hour.

P.S. Don't forget to mark the steering wheel and the column before you take if off otherwise lining it up again is a little bit of a pain.

it is the switch dont even bother checking or testing just replace it

Actually ...

The switch is not electronic on the 91 and I dont't know about the 92 but I heard they are the same. I do not know about the switch with integrated cruise control, my switch is bottom basic without cruise.

I just had the one from the Autowrecker do the same thing, go into a steady buzz. I pulled it apart to find out if it was something that could be fixed either by myself or an electronics shop considering the cost of a new part ($229.99 Canadian)... it was worth a shot.

There are two boards in the switch, the turn signal one is the lower one, gently remove the screws and flip it over. There is a rocker switch that creates the contact depending on which way you are turning. Carefull not to loose the pin that pushes on this rocker it is located on the main piece you just removed the board from. The rocker comes off easy enough by just slightly pushing the retaining clip that holds it in and pulling the rocker gently out. Violla ... now just use your buck'o five sandpaper to clean the electrical contact points on the board and the rocker. Place everything back the way it was removed, and it should work fine.

The switch is just made up of contact points on the inside. The contact points get dirty and you get the buzzing problem because of the open circuit, much the same way a burnt bulb opens the circuit. There are no Electronics, so if you have a little patience and some sandpaper, it can be good as new for less then a mechanics fee.

Hope that helps!!!!

There are also some pretty obvious soldered wires on the turn signal switch. I had the same problem, noticed the broken solder point and the loose wire, and resoldered it. It fixed the problem.

How do I start to access the switch? Does it require pulling the steering wheel off?
Left blinker on constantly.
