It can be the thermostat giving you an over heat or the fan switch on the thermostat attached to the radiator is not working. as for battery light there is a problem with the charging circuit, could be a faulty alternator or a damaged wire or bad earth. you will need to have it checked. if you have a meter put it on volts and check the batter before and after before you start engine and then when the engine is started should be 12-13 volt with engine off ( fully charged battery) with engine running 13.83- 14volts.

Brake light& battery light keeps coming on now car won't start


Anytime the battery light on the dash comes on is an indicator of the alternator not charging, resulting in a dead battery. Low voltage will cause other warning lights to come on as well. Replace the alternator and fully charge the battery before running the engine, to avoid full field condition with the new alternator ( overheating).

Brake light and battery light both on?


If these lights are on even when the vehicle is running, then I would check your battery state of charge. Most parts stores can do this for free, and also check to make sure your brake fluid isn't low. Low brake fluid in the master cylinder reservoir will cause the brake light to come on because there is a fluid level sensor in the reservoir. If the fluid is low, it could mean that you either need brakes, and/or you could have a brake fluid leak. I hope this info helps!

When the Air conditioner is turned on, the check engine light will come on dashboard. If the Air conditioner is turned off the light goes off also.


check your level of trans fluid if low fill then check air hole on top of trans and make sure it is unblocked...if they get blocked it will cause your trans to overflow your fluid causing loss and overheating you fluid causing light to come on...the air hole is usually a rubber or plastic tube sticking up at least 8 inches from the top of the trans

WHE THE CAR MOVES THE BRAKE LIGHT COMES ON FOR A FEW SECONDS ND THEN IT TURN OFF. ALSO METERS IN THE DASH ARE STUCK AND I CAN;T TELL IF ITS OVERHEATING OR IF AM LOW IN FUEL.


Hello

The break light coming on is PROBABLY low brake fluid. When you take off, the fluid moves and the little switch is making. I wish I could help you with the meters on the dash but I am stupid when it comes to that stuff.

Checking the brake fluid is easy, and most gas stations have a can of fluid for a few bucks. If you are thrifty then walmart or kmart generally has it cheaper.

Best of luck on the dash

The low coolant light is coming on periodically but the car is not overheating. What's wrong


The low coolant light is turned on by a sensor in the coolant reservoir when the fluid drops below a certain level. If your reservoir is full, the sensor may be shorted. Assuming the fluid level is good, try taking the connector off the sensor. If that puts the light out, replace the sensor.
