Had the same problem with a Ford Contour. Turned out to be a loose connection on the turn signal switch. remove top trim from steering column and dsisconnect and re-connect connectors. Good luck.
Change out the switch. Bad switch!!
A "dimmer" switch will change the brightness of lights.
When this happens, wiggle the turn signal stalk. If this fixes the problem, you need a new turn signal switch. Sometimes when you hit the brakes, the lights will come on. This is an indication of a bad switch.
A bad brake light switch or a bad headlight switch, or the power source of the fuse has a problem or break in the wire (circuit).
Too much grease in the switch you use to turn your lights,,,dealer charge 500$ to change that switch I have a solution the with 22$ you fix your problem
As this is an intermittant problem it is more than likely the brake light switch is sticking at times..
Check your headlight switch. Sometimes the switch goes bad and the dash lights won't light. Replace the switch for the fix.
Bad switch inside the steering column.
i had the same problem with my 88 trofeo, there is a little box behind the brake peddle don't no what its called but when its pressed, the switch is activated and lights come on,the switch on your car is stuck, its not hard to change it took 5 mins 4 me, so hope i can help... (n e 1 with an 88 trofeo email me because i have some questions ace of heartsokc@yahoo.com)push the twilight switch all the way to the left and turn the lights off that's what i do
You either got a bad new Switch or more likely you have a power supply problem to the park side of the switch.
try replacing the dimmer switch they sometimes go bad and do not allow voltage to the lights
Had the same problem with mine. The dealership told me it was the backup light switch. I had the same problem, as do 99% of VW beetle owners. There was a recall on the Brake Light Switch. Call your dealer and they should change it for free. I did. It worked for a bit, but now i think one of my brake lights is out again.
