Maybe my climate control??? Please help

[jewelz]

I have a 2003 marauder and I can not turn off my heat/AC. Even when I press off it still blows(Seems like it blows more) I can control the speed and temperature from the steering wheel. But only way for me to really turn it of is to pop the hood and unplug it. I was told it may be the climate control? Do anybody Know what the problem could be? Before I buy a new climate control. Thanks in advance

Have you tried running the EATC Module Self-Test (http://www.mercurymarauder.net/forums/showthread.php?t=58956) to see if any DTC's show up jewelz?

Could be:

I had the same issues with my EATC, something wrong in the electronics; ended up replacing the head.

Mine just started doing the same thing, I assume the head unit needs to be replaced?

Anyone have a good one for sale?
