I've got two problems that come and go. first is my speedo at times i well be driving and the speed just drops to zero and the come's back, and other times i have to disconect from the trany and reconect to get it working again. second is my in-dash brake light flashes 8 times and then stays solid for a few seconds. the funny thing is when my brake light on the dash start flashing i loose my speedo but when i get my speedo back working the dahm light stays flashing for a while then goes away. this happens about every three months and I want to know how to fix it.
