heating and abs problems
The ABS light can be a sensor, or the unit. Sometimes even a dirt plug causing a bad connection. Also don't leave out fuses, check them first. My buddy tested my car, which has the ABS light on, and it actually SAID which sensor was bad, both fronts really
I have a feeling it's due somewhat to a previous owner. I think he had line lock. Anyways, a good shop should be able to hook it up to their scanner and tell you. I don't think a parts store's scanner will do it, since I own one of those and it doesn't tell me.
