    Hi All,

    On my 2005 I started having issues with my blower motor not coming on. I first checked all the fuses and relays before I went up under the dash. When I did, I "bumped" the housing and the fan came on and worked fine the rest of the day. The next day when I got in it, it wasn't working again. I tried bumping it but nothing. So I pulled the glove box out and removed the cabin air filter, just barely touched the squirrel cage and it started working again (for the rest of the day). Because of this, I determined it must be the blower motor and not the resistor because while it's working, it works on all speeds with no problem.

    The blend door... I've kept the glove box off in case I run into this problem again, I can just "spin" the wheel and it will work (blower motor on order). BUT I just noticed my blend door is staying in recirc mode even if I choose fresh air. It was working fine just a few days ago. The door DOES function. When I turn the car off it closes normal and when I start the a/c it opens for recirc. When I choose fresh air on my MFD it does nothing.....

    Any ideas???
