Hi fdkassik,
Welcome to the Heartland Owners Forum and to the family. We have a great bunch of folks here with lots of information and all willing to share their knowledge when needed.
Call Heartland Customer Service, 574-262-8030 or 877-262-8032, with your VIN and they can give you the dealer you need to take it to. Or they maybe able to recommend a independent repair service to take care of your problem.
Also be sure and check out our Heartland Owners Club. Join us at a rally when you can and meet lots of the great folks here and make friends for a lifetime.
Enjoy the forum and your new unit.
Jim M
