Yep, here is the code definition - C0550 is an internal malfunction in the ABS/traction control module. Here is the location of the ABS module and how to replace it in the images below. Please start a new thread for the one that has to do with the HVAC system, and we only handle one problem per thread. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
