Hello i have a 2002 gmc
envoy slt with automatic a/c and the heat went out. so i changed the blower motor control module and replaced it with a modifying kit because they dont make that part for my vehicle and while replacing it the fuse blew so i replaced the fuse and now it doesnt work. However i do have rear heat and when i turn the control head to auto i can feel a little bit of air not much though. Please help me figure this out.
