[Legacy Man]

I just noticed another symptom. The keyless door locks don't work if the switch is acting up. What on earth does Chevrolet have running through this switch? There are no aftermarket accessories on this vehicle and I am baffled as to why this is going bad, again. Is this a common problem with Trail Blazers? It's acting up more and more. I'm going to have to replace it this weekend before it costs me a tow bill. I used to work on Honda's and I have the tools, I'm just not sure if the switch is located behind the key cylinder or somewhere else on the column. LM.
