You have a loose wire or a short somewhere in the dash. Hopefully you can fix without changing the harness out. I'd try some test to try to isolate the problem. with the engine off, and the lights on and radio on, reach under the dash to where your fuses are located and lightly move the wires coming from the fuse box watching and listening for the short. If you cant locate here, move your hand deeper into the dash again lightly mving the wires behind the radio and then the light swtich. good luck of finding this.

Have you checked your voltage regulator output? Sounds like as you add load to your electrical system by using more power (such as with the headlights) your car may be losing voltage now. If your car battery does not show a steady 14 to 15 volts charge or so to your battery while your car is running, (and with headlights on) you probably have an alternator and/or voltage regulator going bad. Any good car parts store can easily check that for you. If it is 12 volts or less you need to fix that.

If your car does have a bad short however, your battery likely goes out overnight while the car is sitting there turned off, or you get fuses blowing. Does that happen?

Im sure you just have a short or loose wire in dash! Check fuse panel for corroded or loose fuses!

Look for a vacuum leak in the small hose going into the inside of the cabin from the engine.

94 cutlass supreme died and wont start


See if you can jump start it and have it stay running. If you have gauges on the dash, check the Alternator gauge to make sure it's charging good. It doesn't take much juice to keep the radio going so don't assume the battery is good.

How do i read the check engine codes on a 95 cutlass supreme


If it is OBD-1 you can use a paper clip to jumper two terminals in the test plug under the dash, and then watch the check engine light flash. If it is OBD-2 you need a code reader or scanner.
Most auto parts stores will read OBD-2 systems for free in hopes of selling you some parts.

sounds like a bad or loose ground wire, it would be located in the trunk near the tail light assembly, the other switch is for the cruise contro, it's what cuts the cruise when you hit the brakes.

They are unrelated. Just make sure your brake release is fully relesed. The switch turns the light on if the release isn't against it fully.

1994 oldsmobile cutlass supreme will not start.security flashes


Sounds like a RFID issue. Your key most likely has a chip inside of it. Most of the time people will have multiple keys on their key chain that can cause interference with the receiver in your steering column. Try using the one ignition key to start.
