Searched...no luck. Here goes:

98 Civic LX auto daily driver. When it's below 10 degrees or so, the brake warning light will come on. Fluid is fine, pedal feels fine, all lights are fine. 20 minutes into the trip or so and the light turns off. I've always had '80s Hondas, so I'm not sure what else to check. Anyone else have a similar problem? tia

 

You can check the switch on the E-brake handle under the center console. I don't know why the cold would make it stick, but it might.

 

Yeah I leave it down all the time, so that shouldn't be it. I hope not, anyway.
