I just got a 2002 S10 extended cab LS truck and i have a question on the AC defrost. In most vechicles i have had, when the Defog is turned on the AC comes on to help, and if it does not come on, other vehicles have a AC button to push and turn it on. It does not seem that this truck does not have ether of these features. When i turn on the defog only non AC air comes out of the defrost vents, AC compressor is off. Question? Is this normal or is there a problem with the system.
Thanks
