I have a 85 gt W/ factory A/C, I'm having issues with voltage draw on the battery. If i leave the HVAC in any other position than OFF, such as vent or defroster, while the car is off it draws over 1 amp while the car is sitting if i turn it off and check the amp draw i get around 45-50 milliAmps. Trying to see if anyone else has had this problem and knows how to fix it other than just making sure the HVAC is turned off because sometimes i forget to do it and it will kill the battery before i drive it again. Thanks in advanced.
