I am currently experiencing this same problem and also suspect the alarm. I say this because even though the dash light is blown, when I arm or disarm the alarm, the dash light still goes on. Out of curiousity, when everything is off, and you press the brake, do the dash and taillights go on?
Lemme know if you solve the problem, and I'll let you know if I solve mine.:thumbup:
