Try these guys. http://www.modulemaster.com/en/index.php
You choose your make in the upper left corner and then the model and year. I already checked and they can rebuild this unit, but before you do you should check wiring. More specifically hot lead and ground as well as class 2 data line (I don’t know the com system in this vehicle. do some research.) Is the ABS light on as well?
If you don’t feel confident doing any of this your self find a mechanic and get a second opinion, but if it turns out that it is the EBCM that is bad these guys are the way to go.
Good luck let us know what you find out.
Ooh… I just looked again there is quite a few different EBCM’s that could be in this car you will have to look and see which one it is.
