1990 Toyota Corolla Question: Burning up brake light switches

 

Question

Stew, 1.6L 4 Cylinder, Gresham, OR, October 21, 2009, 22:25

This car is continuously burning up brake light switches. The fuse blows as well. It'll work for a day or two but then it happens. I rewired all the way from the switch back but to no avail it still happens. Could someone please give me a few ideas on what could be going wrong or maybe suggest a place to start investigating

Thanks,
Aaron

    There may be a short from the switch to the brake light bulbs. When the switch is replaced, do all the brake lights function properly?

    Are the bulbs original type or aftermarket? Is the brake light switches your using from Toyota or are they aftermarket? Do you know how many amps the brake lights are drawing when activated?
