Is it possible for a hitch installation package to be the reason my heater no longer working? Wiring harness mess up?
What is your question?
I rarely used my heater in my 2016 Jeep Compass. Lived in San Diego, didn't need it much. Had a hitch package installed for a move and suddenly it doesn't work. Is it possible that when they set up the external light plug for the trailer, they snipped a wire(in the harness)that would affect my heater from working?
RepairPal Certified shops can diagnose and repair your 2016 Jeep Compass. They provide transparent pricing with a minimum 12-month or 12,000-mile warranty on repairs and services.
Anything is possible -- depends on the parts used, the people installing it, and what might be tampered with.
If it's a Jeep factory part and a Jeep factory tech -- I'd say a problem is unlikely. But, many "aftermarket" folks can tap into the incorrect circuit using a make-shift way to do things... requires some investigation and inspections unfortunately.
