No left brake light

[stahlex]

I have a two light tail light system. One for left side one for right. Both bulbs are good. Left turn signal works but left brake light doesn't work. This is a 2001 CH612. Any ideas?

^{are all the wires connected one could have worn through or broken somewhere. or it might be a fuse being a newer truck}

The right brake light works when I press the pedal and both rear turn signals operate correctly, but the left rear brake won't light. It's the same bulb and wire as the left turn signal.

is there a fuse for it??

if so is it bad

It sounds like the turn signal switch to me. The tractor turn signals and brake lights go thru the turn signal switch. Good luck, Steve

I will check tomorrow.

I vote turn signal switch as well. I hope your style is not the kind that you have to remove the steering wheel to change the turn signal switch. I really liked the days of the old flat dash CH's where you could change the TS switch in under a minute with the right size torx screwdriver.

Like the 500, and 900 series "Signal-Stat"?

Simple and effective.

I think it's the switch also.

switch the bulbs from one side to the other and see if the other side works, if it does, it's the bulb. 1157 bulb? if it doesn't it could be the contacts under the bulb, the two leaded bumps are dirty, on the bulb or the socket, or the spring that pushes them on the bulb is stuck with rust, spray some wd in there and poke at it with a screw driver and see if it moves. the 1157 has two filiments in each bulb, so one can be good and one bad.

Ok Lucerne, looks like you get my vote. This is going to be an interesting fix.

I'm positive it is not the bulbs and it only uses the sealed 3 prong bulb style anyway. I'll check the turn signal switch. The truck has been sitting so maybe the contacts are corroded. Thanks for the help.

The blinker interups the brake light,so if the brake light is out the blinker should not work eather..I think!!

My vote too , it's at least worth a shot and simple ... Try it ?

Turns out I unplugged the connector from the bottom of the turn signal and plugged it back in and believe it or not, the brake light works. Thanks for all the help.
