turn signal woes

[shannondeese]

My M35a2 has truck light front LED signals and rear standard signals. I noticed that my front rh signal isn't working so I put another one on and still nothing. The lh works correctly. Any ideas where to start. I have good ground. Thanks.

I had a similar problem with mine. Took apart the turn signal unit and found a broken solder joint. Went over all joints with fresh solder and all is good again.

Thats what I was thinking. Swap your bad light from side to side and see if the problem travels with the light or stays on the rh side.

I installed a new LED light with the same results. If I use a rear regular light then the rear will flash but the front will not. If I install an LED rear light it will illumintate but not flash the front will still not illuminate. Not sure where to go from here. Kurt are you talking about the turn signal unit on the column?

 

[kurtkds]

yes the one on the column. Did problem develop when you put the LED style turn signal on the truck?

The rear turn signal lamp burnt out so I replaced the bulb. Thats when I noticed the front wasn't flashing. I have a spare column mounted turn signal unit that I will try tomorrow after work. Thanks for the advice. I hope it works. I'd like to drive it again soon.

cranetruck would say to check the grounds.

I had a similar problem on my right rear turn signal. The wiring was all hashed where various technicians had plugged and unplugged the light trying to fix a bad connection.

Turns out that inside the turn signal switch there are separate contacts for each light. The contacts were misaligned and a bit burned. I pushed them back into alignment and polished them with an emery board. Now they work perfectly.

Try that.

Turn signals are fixed. I had a wire inside the loom right behind where they plug into the truck harness that was shorting out. Once I cut and spliced it they all work great. Thanks for the advice. I really appreciate it.
