I have a problem with my brake light coming on my 91 GMC pickup 4x4. The wierd thing is that if I keep the truck below 60 km hr. the brake light will not come on. As soon as I go over 60 km hr. the light will come on. Could this be the speed sensor causing this problem? Any help would be apppreciated.
