Turn signal problem

[dyeager535]

Weird (to me) problem with my K5. Almost finished with it enough to get it's new VIN. I typically start it up and run it once a week or so, to keep it charged up. Just recently, I noticed that the left front marker and left front blinker (in the grille) do not work sometimes. ALL other blinkers do. I believe they work if the hazards are on. What seems to fix it is flipping turn signal stalk to the right turn position, then back to left. Not always, but a few times and it works again.The turn signal indicators in the dash warning that a bulb has gone out do NOT indicate this problem when it is happening.

With a bad ground, I would think the dash lights would show a problem with that side of the truck. With a bad turn signal switch, I would think it would be the whole side that did not work. I "jiggled" (hope I'm not getting too technical hehe) the firewall connector, and it made no difference...I've had it apart and cleaned up/regreased the contacts there also. I'm concerned because its intermittent, and gives no warning that it is occurring, which could of course lead to a nice ticket. I know how fun intermittent electrical problems are to solve, but I'm hoping someone here has either had the problem and fixed it, or has intimate knowledge of the electrical system, and can say "no, your theory about X NOT being the problem is incorrect" so I know where to start looking for the problem. Thanks!

Although I am not one of those people you were hoping ot get an answer from, but Iwould trace the wires from the switch all the way to the signal. I bet there is a bare wire or loose connection somewhere. Also, Have you tried changing out your flasher unit?(the little round metal fuse thing that goes in the fuse box) They are only a couple buck and couldn't hurt to start there also.

I appreciate the reply anyway! Yes, I can try the blinker unit I guess. My thoughts on it were that it had only two connectors, so that shouldn't affect one fourth of the total signals of the truck...but hey, like you said, it can't hurt to try another flasher. I have plenty of them, and it's easy and quick to do anyway. Thanks!

have you tried adding some turnsignal lube you can find it in the earlier post great source 4 hard to find parts lol sorry could not help it i had to do that.
have you checked the bulbs in front? maybe they are not getting a good conection turn them on and use a tester on the wires and see if they are getting a signal

Could be as simple as bad bulb connections. The easyest way to get to them is to remove the headlight covers Then loosen the grill so you can bend it out and get your hand behind the grill-lights. The bulb is in the twist out socket. You twist it a quarter turn and it comes out with the bulb. The bulb has two functions (2 glow-wires) Park and turnsignal. Maybe you will also find a corroded wire in the process, they are pretty exposed to the elements upp there.
Hope I helped some.
