Here's a fun one. I just picked up a 91 Accord LX 4 dr auto. The "S" Light flashes while driving. The Speedo, Odometer and Trip meter for the most part don't work, but will kick on randomly for anywhere from 0.5 - 120 seconds then shut back off. My local specialty shop said to check the Speed Sensor. I did some reading on other threads that mentioned the TCU but the car is not having any trouble shifting.

Next Electrical problem- The intermittent setting on the wipers just turns the wipers on; there is no delay between wipes. When the wipers are turned on the only way to get them to turn off is to turn them to high then twist the **** to off right as the wipers get to the bottom of the windshield. The wipers being turned to intermittent will also cause the dead speedo needle to jump up to about 35 mph. I'm thinking its got to be the switch right?

And the 3rd. The blinkers and headlights both work. My drivers side turn signal was doing the fast blink, which after reading the archived posts I found out was just a loose ground. But if the headlights are on and I turn on the left turn signal it shuts the headlights off. I'm thinking this would be a short in the switch as well.

Any thoughts from those of you who have seen these things happen before?

 

So I tightened up some grounds in the wiring. Now the headlights stay on when the left turn signal is on, but the instrument panel lights go out when the right turn signal is on...

 

The S light flashing is noting that your speedo sensor is dead, i wager ur speedo will die from time to time, which may or may not make your car not run properly, also it will affect your odo..
