1994 toyota pick up 4x4 5spd 2.4l
Every time I use the blinker on my truck, on the first blink my speedometer will go to 0 and then back to where it was. the blinkers operate normally and it only happens on the first blink. I have torn apart the gauge cluster and all the connections look tight and clean. Does anyone have have an idea of what to check?

That's an odd one.
Is it an electronic speedo or cable driven?
could it be possible there is a bad ground in the cluster? if im not mistaken the blinker shorts the battery right?
1994 should be electrical like my 93. It is a ground somewhere, still haven't found out where so I can fix mine but it is a common problem. My speedometer reads high but sometimes when I hit the blinker it drops to normal or 0. It appears that the blinker and speedometer share the same ground by looking at the electrical diagram. :headbang:
i was thinking it might be a shared ground, but as i don't have a wiring diagram, i couldn't locate it. It's really not a problem, i am use to it happening. I just thought i would see if anyone had the same problem and was able to fix it. Thank you for your help.
