Turn Signals

With the colder weather finally moving in, I've been experiencing my truck in a whole new way. For instance, the turn signals seem to have trouble function in the lower temperatures (below 32F). The right one will work just fine, but the left seems to not want to "click" into place. Once it does, I can hear the clicking from the flasher, but the dashboard light is not showing the arrow. As far as I know, neither is the outside of the trouble. After about five seconds, it will flash at the normal pace.

I've heard something about there being a spring that wears out? How would that only effect one turn signal? Like I said, the right signal works like it always has. If it helps, I'm also pretty certain the left turn signal won't automatically disable after a turn. I remember seeing some brown gunk built up a the bottom of the stalk, but thought it was only surface rust along the chrome.

Is this something that can be fixed with some lubrication, or do you think it needs replaced? Will it get worse? Right now, I know enough that on colder mornings I need to be extra mindful of my turn signals.

Thanks.

Best to replace the turn signal switch but they're kind of expensive; some guys replace just the cam that breaks, you can purchase replacements at the HELP! section of auto parts stores.

Look at this link; I realize it's for Chrysler but it shouldn't matter, it's just background information.

Concerning the dash light & flasher misbehaving, check your bulbs on all 4 corners.

Nothing works in my truck unless the ignition is returned to the run spot. This includes turn signals, the blower fan, etc.

Make sure all the lights actually work at all the corners....

Yes, I always manually turn the key back a small bit to get the turn signals to work. I verified this morning that all the lights work, and, contrary to what I previously stated, once the flasher begins clicking the lights are illuminated on the outside of the truck. It's only the gauge cluster that lacks a light immediately.

Mine does the exact same thing on occasion, but I believe mine is a short in the wire to the light in the cluster.

EDIT: It could also be that your front turn signal doesn't work for a few seconds. The indicator light in the cluster only monitors the bulb in the front. At one point in time my indicator went out, and after replacing the bulbs in the dash and the front of the truck (the one that was out) I found there to be a short in that wire too. I simply ran a new wire from the steering column harness to the harness under the hood for the turn signal. The rear still worked fine, however.

Just wanted to give a little update...

It seems the cold weather claimed my turn signals as a victim. About a week ago, the stalk snapped. It didn't break off, but it no longer holds in either the left or right turn position. I have to hold it in place. It's not a huge problem, but something I would like to get fixed once Spring comes around.

I'm assuming that whatever plastic clips allow this motion snapped and by replacing the turn signal switch all will be well in my world. The ones I've priced online range from 55-100+ dollars and I just don't have that kind of money right now for something that isn't necessarily broken.

When you do replace the switch, be careful not to pinch the wires when reinstalling lower steering column cover. The wires are very fragile, and pinch easily. I accidentally pinched one wire when i replaced my switch and had to do it all over again.
