This has been bugging me for awhile but since I rarely drive the wife's 2006 Town Car, it hasn't demanded much attention. 
The blower motor only works on high. I drove it yesterday and realized it is a PITA with it being on high all the time. Today, I attempted an EATC diagnostic but to no avail.
I've always said the wife only needs max heat or max AC, so I guess it doesn't really bother her.
Looking at AllData, the blower motor speed control is in the engine compartment behind the engine next to the evaporator housing. Not the easiest place for access, so I thought I would post here for any encouragement, experience, tips or diagnostic help. I refuse to pay the dealer to look into this.
And does anyone know why the EATC would not do a self diagnostic? Could it be the EATC is at fault? Again, looking at AllData, the symptoms point to the blower motor speed control but the last line in the troubleshooting procedure is to replace the EATC.
