I have a 2011 dodge ram 1500 and I am having trouble with my brake lights staying on my cruise control doesn't work and the TCS light stays on. could this be a instrument cluster problem?
It doesn't sound like a instrument cluster problem. First I would check the brake switch or replace it. That's more likely the cause than the IC.
I already replaced the brake switch. what about the clock spring?
It is very unlikely that the clock spring will keep your brake lights on. I would check for a short of the wire harness by the trunk.
TCS can be ON due to the clock spring. But then you have two different issues going on.
