Assuming you have a Winnebago, you can call the Winnebago service #
For inquiries related to your current vehicle, service, or dealer inquires, please have the following information ready when making your call:
"¢ Complete 12 digit serial number
"¢ Date of purchase
"¢ Selling dealers name
I dont think you really need the selling dealer name or the date of purchase. If you are not the original owner you can register with Winnebago too. The other thing you can do is look up the coach specs. This is the web site for winnebago
. Under the "resource tab go down to the manuals and diagrams and input your coach info. That will tell you if you do have a switch for the compartment lites and then ya can call Winnie to find out where.
