Blower Motor full on?

[agray56]

1992 MTX, blower motor is full on, cannot adjust fan speed. Did self test on system, came up no codes. All other functions work, including air, etc. Any ideas?

I believe that would be the blower control module. If you take the glove box out, they'll be a little black box floating around in there. Not sure exactly where, but you'll see it. Chances are its fried. You'll need to find one from a junk yard or see if anyone on the board has a spare. Also, i'd check the drains below the windshield to see if they're clogged up. Thats what happened to me which caused rain to spill into the car behind the firewall which ended up frying my BCM. good luck.

They are $150 from Ford.....you can nab one out of any Lincoln towncar, mercury sable, or Taurus with an EATC. It is underneath the glove box....

Here is a pic of it:http://smg.photobucket.com/albums/v609/berettaboi/?action=view&current=IMGP2417.jpg

And here is a good thread that walks you through where it is and how to change it....http://www.shoforum.com/showthread.php?t=50683&highlight=BCM

The search feature is a wonderful thing.

Hate to bring back a dead thread but when i go to ford to buy one of these things do i ask for a blower control module? Does anyone have a part number or another source i could order it from? Mine is doing the same thing and i thought it was the eatc but this shows me otherwise. Thanks for the help guys. Karson

well the dealer's parts depatement has a highly detailed parts catalog to find the part you need, and the related parts assosiated with it.

if you say 'blower motor control module', HVAC fan speed controller, 'that part in the blower motor assembly', they should know what you are talking about.
