Have driven the car 4-5 times so far this year after the winter and yesterday 5 codes came up. All are history codes. I have done some research on here, but because many threads post the all the codes, it hard to find what I need. Here is what I have found...


p0327 - knock sensor

u1000 - communication loss; probably due to battery disconnect or poor/bad battery. I had disconnected the battery over the winter and brought it inside (non-heated garage). The volts reading on the DIC doesn't stay "steady" when braking or rolling down windows, etc (it will drop to 13.x)... Im assuming my battery is going bad. When cruising, its at 14.1 - 14.3 volts. I have hooked the battery up to a tender to bring it back to full charge. Opinions? Any other causes? Could it be the alternator?

c1217, c1282 - traction control; I couldn't find much about these. Any input? Can this be fixed without any major cost? The traction control and ABS lights are on. Not a huge deal to me since I only drive on sunny days and rarely "race".

b0446 - right actuator; prob either bad or out of sync?.
I assume this is the passenger side? Does the actuator need to be replaced or just "reset"? Read something about rotating the gears or something so it starts at a different position? This would explain why the passenger side does not blow cold. I see you have to take the dash off to get to that actuator... sucky. Costly fix?

Thanks for any advice/opinions!
