Shawn here again and I'm just loaded with stupid questions... Blower motor... runs some times and not others... usually isn't running when I start the truck but after I hit a bump it fires up...its working less and less as the days go on and today it snowed and I couldnt get it to start at all... someone told me it sounds like theres a short in the blower motor... plus the blower only works on high could these symptoms combined be an indicator of a bad blower motor regulator? I know gmc is famous for their well built blower motor regulators hence the reason I'm replacing one in my wifes 04 gmc envoy... if it is the blower motor do then end up with the wonderful task of removing the entire dash or am I lucky enough to be able to get it from under the hood?
