A/C OR HEATER ITS THE SAME THING.COULD YOU HELP ME OUT WITH WHERE THE VAC. LINES ARE LOCATED IF THAT IS THE PROBLEM,THANK YOU.

Answer
Hi Darnell, some of these cars have an electric vacuum motor to control the hvac controls. check the fuses to see if there is one blown or missing, I think its on the same fuse as the daytime running lights. Let me know what you find. Regards, Keith.
