The blower motor stays on all the time, I must disconect the battery to get it to stop. I've been told that the problem is a faulty Air Control Module, but that part costs $136.00 so I would like a second opinion. Thank you

You woud want to first check the blower motor relay and the switches on the dash used to operate the system.

The blower motor relay could be bad. Do you know it's location and how to check it?

Check the link out below to learn how to test relay. . i couldn't find a diagram of where the relay is located so maybe a quick call to your local caddy dealer would help or search through some caddy owner websites and ask them.
