The turn signals work everywhere except tge right Flasher in the guage cluster. Front and rear work. Left works in tge guage cluster. I've replace the printed circuit, ran a ground wire from the center screw location to the battery ground just to eliminate a bad ground. Switched bulbs to a known good bulb. Still can't get the right blinker in the guage to flash
The indicator lights are actuated by the same circuit that activates the turn signals at all four corners. First remove the connector on the back of the dash cluster. Activate the turn signals. Test with a 12 volt test light the wires on the connector. The known good one will light, and the other either will or won't. If it will, there is a problem in your cluster wiring. If not, there is a problem downstream in the harness that connects to the cluster, or even farther down the line. I can't remember what color the signal wires are so trace the printed circuit from the bulbs to the connector.
Ya, they are out of a 2014 Toyota avalon. They are 8 direction power seats with heat and air. So far I haven't figured out how to get the heat to work. Not sure air is possible. I stall was pretty straight forward. Removed the 4 legs so it sat lower and drilled new holes in the seat track. So I got all the directions, fwd/back up/down, reclines. Kind of a pain to have to recline the seats forward to get in the back but sacrifices must be made, lol. So trying to track down the right signal problem, I noticed my printed circuit doesn't look like the one in the manual. Any thoughts or ideas?
Yours looks like the one for full gauges. Do you have those? If so go buy a lottery ticket because you are super lucky. Look on page 15-11 and you will find it under accessories. But the turn indicator spots will be the same unless they lumped them all on one side. That could explain the issue. The bulb holes are the bottom most openings. Follow the circuits up to the connector. Brian, if you have the factory gauge set, you are golden. Even re-pops are super expensive. Let me search a bit more. EDIT: looks like on the factory gauge pod they put the blinkers at the bottom of the speedometer. So your bulbs are the two outer of those three cavities under where the speedo cable attaches. I think the middle one is the brake warning light. If so the connector cavities would be from left to right bottom: #4 and #6. If the gauge printed circuit is being used with the normal idiot light pod, only one blinker would work.
So if you mean the one with 4 actual guages instead of a fuel guage and 3 lights, yes I have that one. Brake light in-between the blinkers below the speedo. So that being said, I'm still looking for a broken wire somewhere? I tried following the manual to see which wire in the circuit plug would be for the right blinker. But after matching the letters up on one page to another page and tracking those wires to the junction box I got overwhelmed. But if your saying the blinkers are #4 and #6, I should be able to track those to the connector and the problem should be in that wire correct? Hey man, have I said thanks recently? Thanks
YOU GOT GAUGES!!!! Drooool....... .Somebody ordered that car RIGHT! Yes, in the FSM the non-gauge wiring shows dark blue and light blue as the blinker wire colors. The gauges schematic in the accessories section does not. GM is pretty dependable on it's colors so I would figure the colors are the same for the gauge wiring. They are just pinned differently. Just trace the printed circuit back to the connector cavity. [one side of the bulb cavity will be power from the blinkers, the other side a ground]. Compare the wire end of connector to the cavity and you should get dark and light blue wires. Test those and if one is dead then you must follow it all the way back to where the splice is in the blinker wiring. In cases like this, where the wire is buried deep in a harness, you have two choices: find the wire where it is broken and fix it- or run a whole new wire and splice it into the wiring that does work.
