Have a 2003 36' Gulfstream Ultra Supreme. Never had issues with A/C's b4 & don't know anything about them? I do have an issue with the front unit now.Unit works as intended when controlled by thermost...
One other thing Chris, if the relay is welded close; shouldn't my AC NOT Work when I control it with thermostat? Cause I can turn it on @ thermostat and set temperature & it cuts On & OFF perfectly? Looks like, to me, it would have same results of relay on board was bad and wouldn't blow air? Just saying, I don't know anything about these things. I appreciate all ur advice. Thanks
