2005 chevy trailblazer intermiten radio, cluster, back up lights and blower motor failure.
Hello, my name is***** you tell me if all of these issues started at the same time?
Fit the blower motor than the radio and the cluster
Thank you. Most of the time this is caused by a failing ignition switch or a bad body control module. I usually do a voltage drop test of the ignition switch first. If it passes the test then body control module is the problem. I would also start with the basics, like the battery and the battery connections as low oltage can cause this also.
Radio and cluster come back to normal by tapping the dash
Then it can be either one. If it is closer to the steering column then it may be the switch. There may even be a bad connection under there so that needs to be checked also, especially if it has any aftermaket electronics on it.
