'88 300zx Heat/AC issues
Hi, I'm new here so please any help would be appreciated. I have a strange problem here. When car is idleing and A/C is on it blows cold air fine thru the dash vents. When accelerating it then starts blowing heat thru the defroster and dash vents. Then when I come to a stop light it will return to blowing cold thru the dash vents. I have changed all the vacuum lines I coud find in the engine compartment but not the ones going thru the firewall. Any Ideas????
