Customer Question

I have a 2003 GMC C4500 with air ride seats. The compressor is not turning on. I have checked fuses and relay and they are good. Any suggestions
JA: Sometimes things that you think will be really complicated end up being easy to fix with a GM. The GM Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: My air ride seats are not working, compressor does not turn on
JA: Are you hoping to fix this yourself?
Customer: Yes
JA: Great! What have you tried so far?
