When stepping on break light goes on in dash board


Sounds like you have a short in the brake light circuit. Get a professional to look at it as this may indicate something more than a nuisance.

My signal lights in my dash both light up when i apply the breaks and only works when i let go of the breaks


Usually this is a short in one of the sockets that holds the bulb, your brake lights are back feeding power causing your turn indicators to glow on dash when you hit the brakes and will stop the turn signal from flashing when you step on the brake pedal also. Start with sockets on rear and look for any shorted or blackened socket ends.

On my 1990 vovlo 240dl the dash light want come nor the tail lights and only one brake light works but i done replaced the bulbs and checked the fuses what else can cause it


dash lights and brake lights are two different circuts. If one brake light works they both should. Check where the light is incerted for a short problem ( rusty or dirty ) As for the dash lights this is controlled by the light switch see if you have it turned back to dim. If not may be a bad switch.

What fuse runs the tail lights and dash lights. Dash lights come on when you hit the brakes. Tail lights are not working at all


If the dash lights are coming on when you step on the brakes you have a grounding problem. The brake light are seeking a ground through the dash lights and tail lights. Check the ground wire near the rear of the vehicle, follow the wire harness there should be a wire (probably black) that breaks out and is bolted to the body or the frame. It could be the light socket itself but for both sides to fail is unlikely.

I'm having an unusual problem with a 1990 Geo Prizm. When I step on the brake the brake light comes on in the rear. When I turn on the lights the brake light goes out if I'm holding the brake pedal down....


Make sure you have the right bulbs in the right place...Sometimes they will fit, even though they are not right...Your brake light bulb should be a two filiment bulb...If it is one , then there goes your problem...Now if your bulbs are interchangable, go ahead an swap them around, and see what happens...Goodluck....

1990 240 volvo,no brake lights and rain makes it hard to start


The tail light assemblies were a bad design in these cars. You need to take each socket out, and clean the contact points on them. Make sure they have a secure connection, and they haven't caused the bulbs to blow out.

The ignition module is located on the inner fender on the drivers side. I would check it to see if it is getting wet. It will cause the engine to not start.

Rear window break light


You either have a 'single filament' bulb installed in a 'dual filament' brake lamp socket ... OR .. you have a 'dual filament' bulb short circuited internally. Check your rear brake lamp bulbs (supposed to be 'dual filament' - two contacts on their bottoms). When you step on the brake pedal, do your dash lights LIGHT UP? A 'cross circuit' exists between brake lamp circuit and parking lamps circuit.

1990 Volvo DL Sedan Brake Lites Work but Also Come on With Running Lites


Is there a switch on the left side of the dash that has a red lens and a wavy line across it? If so, you have a rear fog light switch and it has been activated, causing your brake lights to come on each time you turn your headlights on. Flip the switch and the rear lights should display only the parking lights with the headlights on.
