Hey guys, I’m new to this forum. Currently in the process of purchasing my first GW 330 ex. When I went to run the a/c and heat I couldn’t get any heat out of the vents, just the fan would blow. A/C seems to work fine. Any ideas what it could be?
At this point anything is a possibility - you'll know more after some further investigation. Truthfully, anything else would be guessing right now.
