I have a 1998 Nissan Frontier. The cruise control doesn't work. It has never worked since I've owned this pickup.
When I push this button up:
I hear a relay click. The light on it does not light up, but I think it's broken/burned out (and the schematic leads me to believe that bulb is not required for the cruise control to work, it's connected in parallel with the coil of the relay I hear clicking).
And when I push it down, I again hear a relay click
After I push it up, I try to set the cruise control by pushing the COAST/SET button on this steering wheel switch:
When I do that (with the Frontier going at a speed which should allow cruise control to turn on), nothing happens. The service manual leads me to believe that a cruise control telltale on the instrument cluster is supposed to light up.
It also leads me to believe that when I push the first switch up and hear the relay click, if there's a problem with any of the switches or it detects some other error, the cruise control telltale is supposed to blink.
I've actually tried to make it detect an error by holding down the steering wheel switches while turning the cruise control with the first switch, and nothing happens. The cruise control telltale doesn't light up.
Nothing I've done has gotten the cruise control telltale on the instrument cluster to light up or blink. It also doesn't light up in "bulb test" mode when you first turn the key, but I don't think it's supposed to.
My theory, without having done any troubleshooting with a meter, is that the steering wheel cruise control switch is bad. The picture above is not the one installed in the Frontier. The one in the Frontier is badly worn out. The lettering on all of the switches is gone.
The horn works fine and that's where the steering wheel switch gets it's power.
