i have a 2001 outback if you turn the turn signal on it will take out the dash lights and gauges.after a little time they come back on. the four ways work and if you unplug them you have no turn signals but the gauges work. i tried a new turn signal switch and ignition switch. there was no change please help thank you.

Hm that type of thing sounds like a ground or other electrical connection issue. Which particular one of course would be the question. Neither the turn signal switch nor ignition switch would really be likely suspects even if the turn signal switch were faulty.

Is it just the lighting in the cluster or do all of the dash lights go out? (HVAC, stereo, etc.)
Does it matter which way the signal stalk is moved? (Up/down)
Have you checked fuses for bad connection?


The hazard lights are powered by a different source since they have to work without the key in the ignition. I would suspect a bad connection powering the dash cluster. The big question is, do the signal lights outside still work properly after the dash lights go out?

Thanks. So I gotta track down wiring issues fml. Why couldn't it be a simple problem (anything but wiring) lol. And yes it is the cluster lights AND gauges that go out.

Does this happen when you use a turn signal on either side, both left and right?

Yes its both left and right, kills the gauges unless the hazard switch is pushed. If you push the hazard switch then the turn signal switch the dash is ok. The turn signals never work regardless

If it was on one side only, I would suspect that a wrong bulb could have been installed at one corner, causing a connection between the two circuits. Now it looks unlikely, unless someone replaced all 4 bulbs with wrong type.
If it's a bad ground connection, could be one for the cluster. In that case, when turn signals are off, there will be a ground path through the turn indicator bulbs. The current drawn by the cluster is small and so would be the voltage drop at the bulbs.

The trouble does indeed sound like a bad chassis ground issue like Naru stated. Try cleaning the battery to chassis ground connection to see if that helps. If that doesn't help then try running a temporary ground wire from the battery to the dash area and see if that changes things. If it does then clean the dash grounding points.
