Heat only works when I turn it to 90 degrees on module. HELP!
Ok so I bought the envoy in the summer and the ac works great. Well it started getting colder out and when I turn the heat to lets just say 80 degrees it blows cold air. But when I turn it to 90 (all the way up) it works just fine. Does anyone know whats going on? Id like to get it fixed before winter. Thanks!
