Just wanted to say thanks again for helping me find that relay. After testing it I found it is not the issue and blower motor brushes were the culprit... Looks like projectSHO89 knows his blower motors! I wish they made those a little more serviceable. I ended up cracking the motor open and soldering some replacement brushes from a drill on so I could have heat until I get a new motor unit. Does anybody know if there are after-market units with replaceable brushes? Thanks
