Question about 1991 Geo Prizm
I just bought a used 1990 DL and found that the brake lights come on when I turn on the running lights and do not come on when I push on the brake pedal. The center brake light on the rear package shelf does work when I push on the brake pedal and doesn't come on when I turn on the running lights like the left and right brake lights do. my brake lights do the exact same thing i will turn on the headlights and the two side brake lights come on when i do not apply the brake pedal and turn off when i do. the brake light in the window functions normally

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....

I would check the switch which is separate from the module that controls the daytime running lamps.
Check for fuses blown for the headlamps.
Also, check for the relay operation by following the wires back to it, if so equipped.
Check for a good ground for the headlamp wires that you follow back to make sure they are solidly connected to a ground.
Good luck on this repair.

Some vehicles only allow the brake lights to work when the ignition is turned on and control this via a relay which may have failed so the function is reversed allowing them to work only with the ignition off. Relays can 'weld' their contacts together causing them to become non-operational.Check in the central (if so equipped) fuse/relay box; if you are lucky the cover will have a diagram of the fuses and relays.If so, locate the relay for brakes, check the part number on it, exchange it with the same part number from a different function and try (while parked) to see if this has cured the problem by turning the ignition on, tapping the brake pedal to see if they now respond.If so, the original brake relay is bad.
