Re: GMC Sierra parking brake light stays on
Went to pick up the trailer today because we have to dyno tune tomorrow and when we plugged the trailer into the truck (the truck was off) the e-brake light is still on. When we got home I unplugged the ONE wire going to the switch under the dash and the light is still on. Any suggestions what to do? Brakes are working fine on the truck, fluid level is correct, e-brakes on the truck work perfectly, trailer lighting and electric brakes on the trailer are good, ... This is getting a little frustrating.
