Purchased my first LC 100, 2003 model, last year around the beginning of winter here in Florida. Early mornings got cold and I might have turned the heat on twice. When I had the heat set on full blast it was blowing cool air and never got hot. I didn't think it was a big deal at the time as it started to warm up. Recently I turned the heat on again and still out. I am now getting ready for a trip north over Christmas. This time the wife and sister in law will need to be warm or I will hear it the entire trip. Has anyone else experienced this issue? I have looked to try and find a solution but no luck. I haven't checked the thermostat, yet. I would like to see if anyone else has has a possible solution before I go to a shop to have it diagnosed.
