check for low alternator charge voltage when heater fan is on if alternator has anything lower then 13.5 volts have alternator load tested.. idead charge voltage is 13.8 to 14.5 volts is alt checks good scan abs codes and see whats up auto computers are very sensitive to voltage loos or overcharging. email me with more if you need help g ps check battery connections if any corrosion puul off batt cables negitive first pull center screw out and check both sides of bolt cables for corrosion if found soak cable ends in baking soda/water mixture to get rid of acid then wire brush cables also check the negative battery cable has a second wire that grounds your chassis. if that wire is hot when engine runs with heater on it means you have a bad body ground turn engine off remve black wire to chassis or radiator support and sand the terminal and sand the metal it attaches to. engine grounds are becoming more of a problem due to the use of more plastic being used means less ground points and aluminum tend to oxidize ground connections faster then cast iron does

Why won't tail lights turn off when I turn my car off 1996 acura tl?
possible faulty brake light switch...sticking....usually located on top of metal arm connecting to your brake pedal. $10 part. There's a rubber bumper that the brake pedal switch hits against to turn off. When the bumper gets old it falls off (you will notice the pieces on the floor when you get in). Without the bumper in place the switch post just goes through the hole that the bumper is supposed to be in and is never depressed and the brake lights don't shut off.

Why does brake light keeps coming on in ford windstar 2002 van?
The brake fluid level may be low in the reservoir. If the reservoir is low it's telling you the brake pads are worn down. As the brake linings wear down the fluid level drops and eventually turns on the brake light. Have a mechanic check your brakes soon. See "Related Questions" below in case the brake light in question is/are the ones in the taillights. Not uncommon for Windstar brake lights to turn themselves on.
