I read the posts. Did not see my specific issue. My blower motor doesn't work on 1 or 2. It does work on 3,4 &5. I already replaced the indash controllor as I thought it could be the switch wearing out. Inadvertantly found out some things aren't meant to be dissassembled. 
Any suggestions before I try to take the blower motor itself out?
